With the minor league baseball season coming to an end, it's time for an updated look at how all 30 farm systems stack up around the league.

The following factors helped determine the rankings of players and teams:

• Potential (Player): Potential trumps production a lot of the time, especially in the lower levels of the minors and with recent draft picks. Skill set and overall tools are often a better indication of what kind of future a player has.

• Talent (Player): As for guys in the higher levels of the minors who are close to breaking through at the big league level, production and current talent level are the determining factors, as they are viewed as a more complete product.

• Overall Depth (Team): Having one or two elite prospects is great, but having a deep farm system from top to bottom is the way to build a sustainable contender. The overall depth and level of talent was the biggest factor in ranking each team.

• High-End Talent (Team): That being said, there is a difference between a prospect who has a chance of making an impact at the big league level and a prospect who could be a star. Elite prospects served as a tiebreaker of sorts when two teams were close in the rankings.

An updated list of the top 10 prospects for each team has been provided, as well as some general analysis on top prospects, recent draft picks and the outlook of each farm system as a whole.

It should be noted that players on the big league roster who have not yet used up their rookie status (130 AB, 50 IP, 45 days on roster) were included as prospects, though players on pace to surpass those marks before the season ends were not included.

Note: MLB.com's Prospect Watch served as the baseline for each team's list of top 10 prospects and each prospect's ETA, though changes were made to both along the way to reflect my own opinion.

Overview

An aggressive offseason cost the San Diego Padres a number of their top prospects, and with Austin Hedges and Cory Spangenberg also exhausting their rookie eligibility, this is a significantly different-looking system than it was a year ago.

The team's 2013 first-round pick, Hunter Renfroe, is now top dog, and he should be ready to contribute at some point in 2016 after posting a .783 OPS with 27 doubles and 20 home runs in the upper minors.

Colin Rea and Travis Jankowski have both seen time in the majors this year and could be in line for a spot on the Opening Day roster, and longtime prospect Rymer Liriano is on the cusp of breaking through as well.

Despite not having a first-round pick this year, the team was able to add a pair of high-ceiling arms in the second and third rounds in Austin Smith and Jacob Nix to help bring some pitching depth back to the system.

Overview

Another injury-plagued season by one-time uber-prospect Dylan Bundy drops him from the top prospect spot in the Baltimore Orioles system, coincidentally for another pitcher who was sidelined with arm troubles this year: Hunter Harvey.

It may not be long before 18-year-old Jomar Reyes overtakes them both as the team's top prospect, as he hit .278/.334/.440 with 27 doubles, five home runs and 44 RBI in 84 games at the Single-A level. He's still a work in progress defensively, but he has legitimate middle-of-the-order potential.

D.J. Stewart is a nice addition to the farm system who should move quickly after a standout career at Florida State, but the fastest-rising prospect is first baseman Trey Mancini, who hit .341 with a .938 OPS while tallying 43 doubles, 21 home runs and 89 RBI in 2015.

Catcher Chance Sisco also took another step forward, reaching Double-A at the age of 20. He looks like the catcher of the future.

Overview

Despite relatively disappointing seasons from outfielders Steven Moya and Derek Hill at the top of the system, and the fact that their big prospect pickup in Daniel Norris used up his rookie eligibility, the Detroit Tigers farm system is better than it was a year ago.

Michael Fulmer, the prize of the Yoenis Cespedes trade that also brought right-hander Luis Cessa, had a fantastic season at 10-3 with a 2.24 ERA and 125 strikeouts in 124.2 innings while reaching Double-A.

The team also picked up Matt Boyd in the David Price trade, and he should be in the running for a rotation spot to begin next season.

Throw in the additions of high school right-hander Beau Burroughs and University of Tennessee outfielder Christin Stewart with the No. 22 and No. 34 picks, respectively, in the June draft, and there's more overall depth here than we've seen in recent years.

LHP Sean NewcombAssociated Press

Top 10 Prospects

Overview

Graduating top prospect Andrew Heaney was a hit to the overall profile of the Los Angeles Angels farm system, but a breakout season from fellow left-hander Sean Newcomb gives it another high-profile arm in the top spot.

The No. 15 pick in the 2014 draft, Newcomb went 9-3 with a 2.38 ERA, 1.272 WHIP and 168 strikeouts in 138.0 innings over three minor league levels, finishing up the year with seven solid starts in Double-A.

Christopher Ellis took a big step forward, as the former college closer is showing he has what it takes to stick as a starter while reaching Double-A himself for the first time.

Catcher Taylor Ward was viewed as something of a reach with the No. 26 overall pick in June, but he has hit .348/.457/.438 since signing while displaying the defensive skills that made him such a high pick in the first place.

Overview

After trading away the likes of Anthony DeSclafani and Andrew Heaney, and promoting other arms in Justin Nicolino, Jose Urena, Adam Conley, as well as catcher J.T. Realmuto, the Miami Marlins system has taken a hit in terms of overall talent.

Throw in the fact that last year's No. 2 overall pick, Tyler Kolek, has been something of a disappointment with a 4.56 ERA and 61/81 BB/K ratio over 108.2 innings, and things don't look great.

One bright spot has been the emergence of left-hander Jarlin Garcia, who was left exposed in the Rule 5 draft last winter but managed to sneak through and now looks like a legitimate top prospect.

Keep an eye on this year's top pick, Josh Naylor, as he had perhaps the best raw power in the draft class and could put up some huge numbers in his full-season debut next year.

RHP Edwin DiazJohn Minchillo/Associated Press

Top 10 Prospects

Overview

It's not long ago that the Seattle Mariners had one of the best farm systems in baseball, but with guys like Taijuan Walker, James Paxton and Ketel Marte establishing themselves in the majors and both D.J. Peterson and Danny Hultzen falling short of expectations, things no longer look as bright.

It's been a trying first full season for last year's No. 6 overall pick, Alex Jackson, as he's hit just .207/.318/.365 with middling power numbers. That said, he's still just 19 years old and has tremendous all-around potential.

Left-hander Luiz Gohara held his own in full-season ball at the age of 19, and he has a higher ceiling than Edwin Diaz, but Diaz gets the top spot among pitching prospects after going 7-10 with a 3.82 ERA and 145 strikeouts in 141.1 innings while reaching Double-A.

Tyler O'Neill had a big season with 32 home runs for High-A Bakersfield, while Patrick Kivlehan had 25 doubles and 22 home runs in a full season at the Triple-A level.

Overview

For the second year in a row, the Chicago White Sox scooped up what many considered to be the top pitcher in the draft several slots lower than he was expected to be drafted. It was Carlos Rodon at No. 3 overall in 2014, and it was Carson Fulmer at No. 8 this past June.

That said, it's 2013 first-round pick Tim Anderson who remains the team's top prospect and future everyday shortstop. His glove still needs some work, but he hit .312/.350/.429 with 38 extra-base hits in a full season at Double-A.

Hard-throwing Francellis Montas has continued to impress since being acquired in the trade that sent Jake Peavy to the Boston Red Sox. Whether his future lies in the rotation or at the back of the bullpen, he figures to be an impact arm regardless.

Behind Fulmer and Montas, the team also has the sometimes-overlooked duo of Spencer Adams (12-5, 2.99 ERA, 96 K) and Tyler Danish (8-12, 4.50 ERA, 90 K), who are also capable of emerging as future impact arms.

OF Dalton PompeyMark J. Rebilas-USA TODAY Sports

Top 10 Prospects

Overview

With pitchers Daniel Norris, Jeff Hoffman, Matt Boyd, Miguel Castro, Jesus Tinoco, Jairo Labourt, Alberto Tirado, Nick Wells and Jimmy Cordero all traded at the deadline, the Toronto Blue Jays have sapped the minor league system.

Add in the lost rookie eligibility of Roberto Osuna and Devon Travis, and we're left with almost an entirely new top 10 prospect list from the one at the beginning of the season.

That being said, Dalton Pompey still has a chance to be an everyday center fielder, and Sean Reid-Foley is one high-ceiling arm that the team managed to hold onto.

First-round pick Jon Harris should move up quickly, Anthony Alford has taken a big step forward turning his elite athleticism into on-field production, Max Pentecost still has future All-Star potential despite an injury-plagued season, and Vladimir Guerrero Jr. could shoot up prospect lists once he begins his pro career.

RHP Ashe RussellLenny Ignelzi/Associated Press

Top 10 Prospects

Overview

The Kansas City Royals traded off top prospects in Sean Manaea, Cody Reed, John Lamb and Brandon Finnegan to acquire Ben Zobrist and Johnny Cueto, but there is still plenty of talent down on the farm.

Raul A. Mondesi has been aggressively moved through the system the past few years, and he's responded well every step of the way. His overall numbers aren't eye-popping, but when you consider the 20-year-old just spent a full season in Double-A, that's to be expected. His glove is ready now, it's just a matter of his bat catching up, which sounds an awful lot like what people were saying about Francisco Lindor a year ago.

The two prospects to watch are Kyle Zimmer, as he works his way back from injury, and Bubba Starling, as he works his way back into the top prospect picture. Both have a world of potential, but both have been huge disappointments so far in their pro careers.

If he can improve his plate discipline, Jorge Bonifacio has a chance at being the long-term answer in right field after the 22-year-old held his own making the jump to Double-A.

RHP Tyler BeedeJohn Minchillo/Associated Press

Top 10 Prospects

Overview

With Kyle Crick continuing to struggle mightily with his command and Keury Mella traded to the Cincinnati Reds in the Mike Leake deal, the San Francisco Giants have some new names at the top of their prospect list.

Tyler Beede has moved quickly since being taken with the No. 14 pick in last year's draft, and he could arrive in the majors at some point early next season given the significant questions surrounding the big league rotation.

Christian Arroyo is finally living up to his first-round billing after hitting .304/.344/.459 with 28 doubles and nine home runs in 90 games at High-A San Jose.

First-round pick Phil Bickford and international signing Lucius Fox give the team two more high-ceiling prospects, but it's the team's other first-round pick, Chris Shaw, who has made the most noise with a .911 OPS that includes 11 doubles, 12 home runs and 30 RBI in 46 games for Low-A Salem-Keizer.

1B Matt OlsonMark J. Rebilas-USA TODAY Sports

Top 10 Prospects

Overview

The Josh Donaldson trade remains a tough one to swallow for Oakland Athletics fans, but the key piece acquired in that trade, Franklin Barreto, has a chance to make the deal worthwhile. The 19-year-old spent a full season at High-A Stockton, where he hit .302/.333/.500 with 22 doubles, 13 home runs and 47 RBI.

Matt Olson, Renato Nunez and Matt Chapman all entered the season as established top prospects and put up solid numbers, while Chad Pinder enjoyed a breakout season in Double-A, where he hit .317/.361/.486 with 32 doubles, 15 home runs and 82 RBI.

First-round pick Richie Martin and third-round pick Dakota Chalmers both have solid upside, while Sean Manaea, Jacob Nottingham and Casey Meisner were all added to the mix in deadline trades.

RHP Luis PerdomoJohn Minchillo/Associated Press

Top 10 Prospects

Overview

Graduating outfielders Stephen Piscotty and Randal Grichuk from the prospect rankings and trading Rob Kaminsky sends the St. Louis Cardinals down several spots in these rankings, but there is still no team better at drafting and developing talent in-house.

Also, they do still have one elite prospect in right-hander Alex Reyes, who has quickly climbed into the conversation with Lucas Giolito, Julio Urias and Tyler Glasnow for the title of top pitching prospect in baseball. The 21-year-old went 5-7 with a 2.49 ERA and 151 strikeouts in 101.1 innings while holding hitters to a .197 average.

Jack Flaherty, the team's first-round pick in 2014, quietly had a nice year in Single-A as well, where he went 9-3 with a 2.84 ERA and 97 strikeouts in 95 innings.

The guys to watch will be the young trio of Magneuris Sierra, Edmundo Sosa and 2015 first-round pick Nick Plummer, as all three have tremendously high ceilings but a ways to go in their development.

RF Aaron JudgeMark J. Rebilas-USA TODAY Sports

Top 10 Prospects

Overview

With Luis Severino and Greg Bird both expected to lose their rookie eligibility before the regular season wraps up, the New York Yankees system doesn't look quite as good as it did heading into the season. That said, the whole point is for guys to move on and become contributors in the big leagues, and those two have certainly done that.

Slugger Aaron Judge now assumes the role of the team's top prospect, though speedy shortstop Jorge Mateo is not far behind after the 20-year-old hit .278/.345/.392 and stole 82 bases while reaching the High-A level.

Rob Refsnyder and Gary Sanchez both have little left to prove at the minor league level, and Eric Jagielo is getting close as well after a strong full season in Double-A.

The emergence of Rookie Davis, a 14th-round pick back in 2011, has added another arm to the top prospect mix. It's 2015 first-round pick James Kaprielian who is expected to assume the role of the top arm in the system next season, and he could move quickly.

OF Bradley ZimmerCharlie Neibergall/Associated Press

Top 10 Prospects

Overview

The continued progress of Bradley Zimmer and Clint Frazier gives the Cleveland Indians two of the top outfield prospects in baseball, and Zimmer could challenge for the everyday center field job as early as next season.

However, the breakout prospect of the year for the Tribe was first baseman Bobby Bradley, who posted an .875 OPS with 15 doubles, 27 home runs and 92 RBI while reaching High-A at the age of 19.

Rob Kaminsky was an absolute steal in the trade that sent Brandon Moss to the St. Louis Cardinals, while Brady Aiken was the biggest risk/reward pick in the draft after undergoing Tommy John surgery. The potential that made him the No. 1 overall pick in 2014 is still there, though.

Their 2014 first-round pick, Justus Sheffield, along with No. 42 pick Triston McKenzie and No. 59 pick Juan Hillman give the team three arms to watch with high ceilings but developmental work to do.

RHP Lucas GiolitoJohn Minchillo/Associated Press

Top 10 Prospects

Overview

In Lucas Giolito and Trea Turner, the Washington Nationals have arguably the best pitching prospect in baseball and a potential future All-Star at the shortstop position.

Both figure to play a significant role in 2016, and both will likely be ranked among the top 25 prospects in the game when preseason rankings roll out next spring.

Those two are enough to earn the Nationals a spot in the middle of the rankings, but behind them the farm system is relatively weak compared to recent years. The trio of Reynaldo Lopez, Erick Fedde and A.J. Cole will go a long way in determining whether they move up or down.

The big surprise of the year was 18-year-old Victor Robles, who hit .352/.445/.507 over 213 at-bats and didn't miss a beat making the jump from the rookie league to Low-A Auburn. 

RHP Jose BerriosTommy Gilligan-USA TODAY Sports

Top 10 Prospects

Overview

The Minnesota Twins come in at the No. 16 spot with the assumption that Byron Buxton will exceed the 130 at-bat limit before the season is over and lose his rookie eligibility. He's currently at 115 and has been splitting time in center field with Aaron Hicks.

With Miguel Sano also establishing himself in the majors, the team's top prospect is now right-hander Jose Berrios. The 21-year-old went 14-5 with a 2.87 ERA, 1.046 WHIP and 175 strikeouts in 166.1 innings, yet he was not among the team's September call-ups.

"An apparent lack of planning on Minnesota's part saw the right-hander toss 166⅓ innings in 2015. But none of them came at the major league level on a club battling for a playoff spot with apparent room in the rotation," wrote Tommy Rancel of ESPN.com.

First-round pick Tyler Jay should move quickly after dominating as the Illinois closer, while Max Kepler was the breakout prospect of the season with a .318/.410/.520 line that included 34 doubles, 13 triples and nine home runs.

SS Orlando ArciaBrace Hemmelgarn/Getty Images

Top 10 Prospects

Overview

One of the worst farm systems in baseball is suddenly knocking on the door for a spot in the top 10, thanks to the emergence of shortstop Orlando Arcia and some good returns on its deadline trades.

Arcia, 21, hit .307/.347/.453 with 37 doubles, eight home runs and 69 RBI as his bat took a big step forward alongside his elite-level defense.

Brett Phillips and Zach Davies were acquired at the trade deadline, along with Domingo Santana, who will likely exceed rookie limits, and all three of those players could play a significant role in 2016 and beyond.

While the system has gotten a bit thin on pitching, Jorge Lopez is a name to watch after he went 12-5 with a 2.26 ERA, 1.095 WHIP and 137 strikeouts in 143.1 innings in a full season at Double-A Biloxi. 

RHP Archie BradleyJoe Camporeale-USA TODAY Sports

Top 10 Prospects

Overview

Archie Bradley was expected to be among the top rookie performers of 2015, and he got off to a strong start at 2-0 with a 1.45 ERA in his first three starts after breaking camp with a rotation spot. He was bit by the injury bug once again after that, though, first taking a line drive to the face and then dealing with shoulder troubles. 

Bradley stays in the top prospect spot for now, but don't be surprised if a number of preseason lists have No. 1 overall pick Dansby Swanson as the team's top prospect. The Vanderbilt star was as polished as any player in the draft class, and he should move quickly.

Behind him are pitchers Aaron Blair and Braden Shipley, who could both challenge for rotation spots at some point in 2016. Cuban defector Yoan Lopez is also on the fast track to the majors.

Infielder Brandon Drury had a big season at the plate with a .303/.344/.412 line that included 40 doubles, and he could push Chris Owings for the second base job next spring.

LHP Steven MatzSteve Mitchell-USA TODAY Sports

Top 10 Prospects

Overview

Despite graduating Noah Syndergaard, Michael Conforto and Kevin Plawecki, the New York Mets still have a farm system that ranks in the upper half thanks to both high-end talent on the verge of contributing and overall depth.

Steven Matz has already made his presence felt at the big league level with a 3-0 record and 1.88 ERA over four starts, but with just 24 innings of work under his belt, he'll likely maintain his rookie eligibility.

Meanwhile, Brandon Nimmo could follow a similar path to Conforto and earn a midseason call-up at some point next season. However, if the team is unable to re-sign Yoenis Cespedes, it's not out of the question that he could be on the Opening Day roster.

Shortstop remains a long-term question mark at the big league level, but someone from the trio of Amed Rosario, Gavin Cecchini and Milton Ramos figures to be the answer. It will also be interesting to see where Dominic Smith fits into the team's future plans, as his development could play a role in whether Lucas Duda is extended.

Top 10 Prospects

Overview

Even with Jorge Alfaro, Jake Thompson, Nick Williams, Alec Asher and Jerad Eickhoff all traded to the Philadelphia Phillies in the Cole Hamels deal, the Texas Rangers still have one of the better farm systems in the American League.

That is thanks in large part to a breakout season from outfielder Nomar Mazara, who signed a then-record $4.95 million international bonus back in 2011 and has turned potential into production this year with an .808 OPS that includes 26 doubles and 14 home runs while reaching Triple-A as a 20-year-old.

Joey Gallo still has as much raw power as anyone in baseball, but until he can cut down on his strikeouts, it's hard to see him being more than a Mark Reynolds-type. He still has time to make adjustments, though, as Adrian Beltre will be back next season.

First-round pick Dillon Tate should move quickly, Lewis Brinson looks like a potential star after hitting .332/.403/.601 with 20 home runs, and 19-year-old Luis Ortiz went 4-1 with a 1.80 ERA in 50 innings for Single-A.

That's not to mention the chance the team took on Duke right-hander Michael Matuella, who was in the running to be the No. 1 overall pick before injuries sidelined him. He could turn out to be an absolute steal with the No. 78 overall pick.

RHP Robert StephensonJerry Lai-USA TODAY Sports

Top 10 Prospects

Overview

Already a talented farm system because of high-end prospects Robert Stephenson and Jesse Winker, the Cincinnati Reds added even more young talent to the mix with the deadline trades of Johnny Cueto and Mike Leake.

Keury Mella and Cody Reed join the mix, as well as John Lamb and Brandon Finnegan, who are pitching in the majors. That's on top of landing the top catcher in the draft in Tyler Stephenson, who has a chance to be a star on both sides of the ball.

While Stephenson and Winker have posted solid numbers and climbed a step closer to reaching the big leagues, the Reds' biggest breakout prospect has been left-hander Amir Garrett.

A college basketball player who is only now starting to focus on baseball full time, Garrett went 9-7 with a 2.44 ERA, 1.226 WHIP and 133 strikeouts in 140.1 innings. His electric stuff was on display in the Futures Game, and he may only be scratching the surface of his potential at this point.

SP Blake SnellBrace Hemmelgarn/Getty Images

Top 10 Prospects

Overview

Led by newly minted Baseball America Minor League Player of the Year Blake Snell, the Tampa Bay Rays again have one of the best farm systems in baseball.

Snell began the season with a 49-inning scoreless streak and wound up going 15-4 with a 1.41 ERA, 1.022 WHIP and 163 strikeouts in 134 innings over three minor league levels.

While Snell gets the No. 1 prospect spot based on performance, shortstop Willy Adames may have the higher ceiling. The prize of last year's David Price trade, Adames posted a respectable .721 OPS with 34 extra-base hits as a 20-year-old in High-A.

Brent Honeywell and Taylor Guerrieri give the team two more solid pitching prospects who could be next up in a long line of homegrown arms in the majors, while Justin O'Conner is still an elite defensive backstop and the catcher of the near future.

First-round pick Garrett Whitley and second-round pick Chris Betts both have big-time offensive upside, and that's obviously what this franchise has been lacking in recent years.

Even with Kris Bryant, Kyle Schwarber, Addison Russell and Jorge Soler graduating from the Chicago Cubs prospect list, the team still has a top-10 system and some terrific young talent on the verge of making a big league impact.

Gleyber Torres is the latest position player to show star potential, as the 18-year-old spent the bulk of the season at Single-A South Bend, where he hit .287/.346/.376 with 24 doubles and 22 steals.

This year's top two picks, Ian Happ and Donnie Dewees, give the team two more solid bats that should move quickly, while catcher Willson Contreras enjoyed a breakout season at Double-A Tennessee, where he won the Southern League batting title with a .333 average.

On the pitching side of things, Duane Underwood (6-3, 2.41 ERA) and Pierce Johnson (6-2, 2.08 ERA) both had terrific seasons, while Dylan Cease has quickly shown why the team shelled out a way-over-slot $1.5 million bonus to sign him as a sixth-round pick in 2014.

RHP Tyrell JenkinsDavid Goldman/Associated Press

Top 10 Prospects

Overview

He may not be a prospect in the traditional sense given the fact that he's 30 years old, but Cuban defector Hector Olivera figures to step into a prominent role for the Atlanta Braves as their everyday third baseman next year.

Speedy Ozhaino Albies is a more typical prospect, as the 18-year-old hit .310/.368/.404 with 29 steals in a breakout season for Single-A Rome.

Pitchers Tyrell Jenkins, Touki Toussaint, Manny Banuelos, Max Fried and Ricardo Sanchez were all picked up via trade since last offseason, and the same goes for center fielder Mallex Smith, as the front office has done a terrific job stockpiling young talent.

First-round pick Kolby Allard may have the highest ceiling of any pitcher in the system, but Jenkins gets the top spot after going 8-9 with a 3.19 ERA over 138.1 innings between Double-A and Triple-A.

SS J.P. CrawfordBrace Hemmelgarn/Getty Images

Overview

The first step in rebuilding is flipping veteran talent for prospects, and the Philadelphia Phillies have finally fully committed to doing that over the past calendar year.

The Cole Hamels blockbuster brought them a trio of players who figure to be key pieces of the long-term puzzle in catcher/first baseman Jorge Alfaro, outfielder Nick Williams and starter Jake Thompson. All three could see the majors at some point in 2016.

Another player on the cusp of making a big league impact is shortstop and top prospect J.P. Crawford, who has all the tools to be a future star. The 20-year-old hit .288/.380/.414 with 35 extra-base hits while spending most of the year in Double-A.

First-round pick Cornelius Randolph has big-time offensive upside, while second-round pick Scott Kingery went straight to Single-A Lakewood after signing and could be among the first position players from the draft class to reach the majors.

SS Brendan RodgersDavid Zalubowski/Associated Press

Top 10 Prospects

Overview

The big league club is still a mess, but the Colorado Rockies have quietly assembled one of the deepest and most talented farm systems in baseball.

Third baseman Ryan McMahon, second baseman Forrest Wall and shortstops Brendan Rodgers and Trevor Story all rank among the top prospects at their respective positions, and alongside superstar Nolan Arenado at the big league level the future infield should be dynamic.

Throw in outfielders David Dahl and Raimel Tapia, and catcher Tom Murphy, and there is no shortage of position-player talent in the organization. But, as always, the issue in Colorado is pitching.

Landing Jeff Hoffman in the Troy Tulowitzki trade, along with a handful of lower-level arms, gives the team a second front-line pitching prospect alongside Jon Gray, who has been slower to develop than expected. Those two will need to both realize their potential for the franchise to take the next step.

2B Yoan MoncadaBrynn Anderson/Associated Press

Top 10 Prospects

Overview

Even with Henry Owens, Eduardo Rodriguez, Blake Swihart, Rusney Castillo, Travis Shaw and Steven Wright exiting the prospect ranks, the Boston Red Sox still have plenty more young talent on the way.

Cuban phenom Yoan Moncada tops that list, as the 20-year-old hit .278/.380/.438 with 19 doubles, eight home runs and 38 RBI in 81 games for Single-A Greenville. He could take a huge leap forward in his second professional season.

Right behind him are third baseman Rafael Devers and center fielder Manuel Margot, who have both emerged as top-50 prospects this year.

First-round pick Andrew Benintendi hit .313/.416/.556 with 11 home runs and 31 RBI in 54 games after signing, and he should move quickly after a standout junior season at Arkansas.

The system may not be as talented at the top as it was a year ago, but it's still incredibly deep and figures to put at least three players among the league's top 50 prospects heading into next year.

Overview

With a big league roster already loaded with homegrown talent in the likes of Andrew McCutchen, Gerrit Cole, Starling Marte, Neil Walker, Gregory Polanco and Tony Watson, the Pittsburgh Pirates have plenty more potentially impactful players on the way.

Towering 6'7" right-hander Tyler Glasnow tops that list as he continues to dominate minor league opponents. In four minor league seasons, he's gone 28-16 with a 2.07 ERA, 1.059 WHIP and 501 strikeouts in 383.1 innings.

First baseman Josh Bell and second baseman Alen Hanson are both ready to contribute at the big league level, while outfielder Austin Meadows and catcher Reese McGuire have All-Star-caliber upside but are still a couple of years away.

Jameson Taillon has struggled to stay on the field in recent years, but he was one of the game's top pitching prospects pre-injury and is still just 23 years old.

As if they weren't already stacked, outfielder Harold Ramirez has been one of the breakout prospects of 2015 with a .337/.399/.458 line and 22 steals for High-A Bradenton.

Even with Carlos Correa, Lance McCullers, Vincent Velasquez and Preston Tucker moving on to the big leagues, the Houston Astros still have a loaded farm system.

That's thanks in large part to their recent draft class in which they grabbed Alex Bregman and Kyle Tucker with the second and fifth overall picks, then signed Daz Cameron to a well-above-slot deal after he slipped to the second round.

A.J. Reed (.340/.432/.612, 30 2B, 34 HR, 127 RBI) and Joe Musgrove (12-1, 1.88 ERA, 99 K) were two of the biggest breakout prospects of 2015, and they join Derek Fisher, Francis Martes and Colin Moran as players on the cusp of reaching the majors.

The above list is impressive, and it doesn't even include second baseman and Futures Game starter Tony Kemp, third baseman J.D. Davis, who had 26 home runs and 101 RBI in High-A, and second-round pick Riley Ferrell, who has future closer stuff.

Overview

The team's decision to wait on promoting Corey Seager means he'll maintain his rookie eligibility heading into 2016, and that clinches the No. 1 farm system for the Los Angeles Dodgers as the 2015 MiLB season wraps up.

Seager has hit .426/.526/.617 with seven extra-base hits in 47 at-bats since being promoted after tearing up Triple-A pitching for much of the year, and he should be the NL Rookie of the Year front-runner to kick off 2016.

Not to be outdone, 19-year-old phenom Julio Urias continued his rapid ascent by reaching Triple-A, and he could be in the mix for a rotation spot early next season.

Jose De Leon (6-7, 2.99 ERA, 163 K, 114.1 IP) took a huge step forward, and he could also be in the mix for a rotation spot, while second baseman Jose Peraza and catcher Austin Barnes have already gotten a taste of the big leagues.

Throw in 19-year-old Alex Verdugo hitting .311/.340/.441 with 32 doubles and nine home runs between Single-A and High-A, and 20-year-old Cody Bellinger posting an .873 OPS with 33 doubles, 30 home runs and 103 RBI in a full season at High-A, and the Dodgers system is absolutely stacked.
