Rosell Herrera, SS, Colorado Rockies
.347/.433/.581, 82 H, 19 2B, 12 HR, 15 SB, 51/34 K/BB (61 G)
The 20-year-old continues to rake in his second tour of the South Atlantic League, as he is currently pacing the league with a .347 batting average. Last 10 games: .375/.419/.575, 15 H (4 XBH).
Byron Buxton, OF, Minnesota Twins
.342/.435/.566, 60 R, 29 XBH (7 HR), 47 RBI, 26 SB, 46/39 K/BB (59 G)
Buxton has shown no signs of slowing down during his very impressive full-season debut, as he’s literally doing it all on both sides of the ball. It doesn’t really factor into his placement on this list, but did you see the 19-year-old’s catch this week? Amazing.
Brandon Drury, 3B, Arizona Diamondbacks
.320/.355/.568, 42 R, 24 2B, 10 HR, 46 RBI, 38/14 K/BB (60 G)
Traded to the Diamondbacks during the offseason as part of the Justin Upton deal, the 6’2” right-handed hitter continues to post big power numbers in the Midwest League, though he does have some swing-and-miss to his game. Last 10 games: .314/.390/.800, 3 2B, 4 HR, 9 RBI.
Stetson Allie, 1B, Pittsburgh Pirates
.332/.414/.629, 16 2B, 17 HR, 61 RBI, 73/31 K/BB (62 G)
In his first season since moving from the mound to the infield, Allie, a 6’2”, 238-pound right-handed hitter, has showcased robust raw power and leads the South Atlantic League with 17 home runs in 62 games.
Dan Vogelbach, 1B, Chicago Cubs
.272/.343/.461, 13 2B, 11 HR, 43 RBI, 48/28 K/BB (62 G)
One of the more underrated pure hitters in the minor leagues, Vogelbach’s plate discipline and approach have been challenged this year at a full-season level, but that hasn’t stopped him from showcasing prodigious raw power. Last 10 games: four home runs.
Albert Almora, OF, Chicago Cubs
.413/.451/.547, 14 R, 8 XBH, 11/5 K/BB (18 G)
Almora opened the 2013 season on the disabled list after undergoing surgery for a broken hamate bone, but has been on an absolute tear since joining Low-A Kane County in late May. The sixth overall pick in the 2012 draft has a chance to move through the minor leagues quickly. Last 10 games: .395/.426/.512, 8 R, 17 H, 7/3 K/BB.
Carlos Correa, SS, Houston Astros
.292/.395/.426, 17 XBH (4 HR), 41 RBI, 6 SB, 41/30 K/BB (50 G)
The No. 1 pick last June has been outstanding in his first taste of full-season ball, as he’s demonstrated a knack for driving in runs and an advanced approach well beyond his age (18).
Corey Seager, SS, Los Angeles Dodgers
.282/.349/.450, 11 XBH (4 HR), 22 RBI, 7 SB, 31/12 K/BB (36 G)
After a slow start to the season and some time spent on the disabled list, Seager has been on fire since returning to action on June 2. Last five games: 9-for-19, 5 R, 3 XBH, 6 RBI, 2 SB.
Micah Johnson, 2B, Chicago White Sox
.328/.412/.496, 59 R, 25 XBH (7 3B), 50 SB (15 CS), 51/33 K/BB (61 G)
A ninth-round draft pick in 2012 out of Indiana, Johnson currently leads all minor leaguers with 50 stolen bases through 61 games, though he has been nabbed 15 times. And after batting .273 in the rookie-level Pioneer League last season, the development of his bat has been a pleasant surprise.
Joey Gallo, 3B, Texas Rangers
.235/.327/.548, 48 R, 34 XBH (18 HR), 35 RBI, 100/29 K/BB (62 G)
Gallo struggled mightily in May with a .748 OPS (low by his standards) and 46 strikeouts in 28 games, but has seemingly turned the corner this month: .326/.341/.814, 4 2B, 5 HR in 10 games. He still needs to tone down the strikeouts, though.
Bubba Starling, OF, Kansas City Royals
.207/.286/.364, 16 XBH (7 HR), 7 SB, 66/19 K/BB (55 G)
Starling is yet to turn the corner in his full-season debut, as his long, inefficient swing has led to 66 strikeouts in his first 55 games.
Cito Culver, SS, New York Yankees
.211/.311/.322, 13 XBH (4 HR), 4 SB, 62/29 K/BB (50 G)
The 2010 first-rounder is yet to develop as hoped, as he continues to struggle this season in his second tour of the South Atlantic League.
Mitch Walding, 3B, Philadelphia Phillies
.244/.319/.317, 14 XBH, 30 RBI, 61/22 K/BB (57 G)
After posting a .721 OPS in 23 April games, Walding is yet to post an OPS north of .600 in any subsequent month. I thought he'd at least start tapping into his above-average raw power, but he has only left the yard once in 462 professional at-bats.
Victor Roache, OF, Milwaukee Brewers
.211/.307/.351, 25 R, 12 XBH (6 HR), 54/21 K/BB (47 G)
Roache possesses some of the best raw power in the minor leagues, but is still very raw despite his college background and continues to be plagued by his propensity to swing and miss.
