Every MLB Team's Potential September Call-Up That Can Make a Big Impact

September call-ups can be major difference makers for a team in contention. They can also be a reason to continue to pay attention to a struggling team.

Young prospects are often given an opportunity to contribute once the rosters expand to allow 40 players on Sept. 1st. Teams get a chance to evaluate how their younger players do against major league talent.

Players who have a good September can put themselves in a good position to make the major league team out of spring training the following year.

Arizona Diamondbacks: Trevor Bauer

Trevor Bauer was the third overall pick in the 2011 MLB draft. He is expected to be the first player from his draft class to reach the majors, and it could happen in September of this year.

Bauer is already flying through the minor leagues as he has already reached Double-A. Bauer has been impressive at every level that he has pitched at.

He will likely pitch out of the bullpen for the Arizona Diamondbacks if he is called up.

Atlanta Braves: Julio Teheran

Julio Teheran struggled in the two starts that he made for the Atlanta Braves earlier this year. However, that should not stop Teheran from being called up in September.

Teheran has continued to show why he is one of the best pitching prospects in baseball with his performance in Triple-A. He continually fools hitters and has absolutely dominated the level. Teheran has nothing left to prove at Triple-A.

Baltimore Orioles: Ryan Adams

Ryan Adams made a short appearance on the Baltimore Orioles roster earlier this season, but he has spent most of the season in the minors. He should return to the majors in September.

Adams has some power for a second baseman, but he does have some contact problems. He has struck out almost once a game during his minor league career.

However, Adams has maintained a career batting average over .285 in the minors.

Boston Red Sox: Felix Doubront

Felix Doubront began the year as a member of the Boston Red Sox rotation. He was then sent down to the minors to be stretched out, so he could become a starter.

Doubront began his career as a starter and has had success in that role at Triple-A this year. He could be a big help at the back end of the Red Sox rotation.

Chicago Cubs: Chris Carpenter

Chris Carpenter had been a starter in the Chicago Cubs system, but this year the team decided to convert him to a reliever. Carpenter has seen some time in the majors this year.

He has spent most of the season in the minors, but he has struggled there. However, Carpenter should still get called up in September. He will pitch out of the bullpen.

Chicago White Sox: Dayan Viciedo

Dayan Viciedo was outstanding offensively for the Chicago White Sox during his 38-game stint in the majors last season. He hit .308 with five home runs and 13 RBI. However, the White Sox could not find a spot for him on their roster this year.

Viciedo has spent the whole year at Triple-A and has shown that he deserves a September call-up. He has had no problem hitting and he looks like a major league player.

Cincinnati Reds: Edinson Volquez

Edinson Volquez is not your typical September call-up. Most September call-ups have never won 17 games in a season at the major league level. However, since undergoing Tommy John surgery in 2009, Volquez has not been the same pitcher.

Volquez was sent down to the minor leagues this year to try to regain his form. He has had a lot of success at AAA and should help the Reds down the stretch.

Cleveland Indians: Zach McAllister

The Cleveland Indians have already called up many of their top prospects this season. There are still other players that the Indians can call-up that could have a positive impact.

Zach McAllister is one of those players. He has already made one spot start for the Indians this year. McAllister has spent the rest of the year at Triple-A and has put up impressive numbers.

Colorado Rockies: Drew Pomeranz

The one thing standing in the way of a September call-up for Drew Pomeranz is the fact that he is not on the Rockies 40-man roster. If he pitches well in August, the Rockies could add him, so they can bring him up.

Pomeranz began the year in High-A ball with the Cleveland Indians. He was sent over to the Rockies in the deal for Ubaldo Jimenez. Pomeranz has been dominant in both High-A and Double-A this season.

Detroit Tigers: Jacob Turner

The Detroit Tigers called up 20-year-old Jacob Turner to make a spot start in July this season. He was impressive in his major league debut.

Turner should get a chance to make a few more appearances for the Tigers this September. He has been outstanding in the minors this year, and if he performs well in September, he could make the Tigers' Opening Day roster next year.

Florida Marlins: Brad Hand

Brad Hand is one of the most promising young pitchers in the Florida Marlins organization. He made eight starts for the Marlins this season and then was sent back down to the minors.

Hand has shown a mastery of the minor leagues. He has been very successful at Double-A and needs more of a challenge. He should be a part of the Marlins future.

Houston Astros: Brett Wallace

The Houston Astros decided to send down Brett Wallace despite the fact that he was having a decent year in his first full season. He had no protection in the lineup and yet still managed to put up acceptable numbers.

Wallace should come right back up to the majors once rosters expand in September. He should be playing everyday once he is called up, but it is not certain that it will actually happen.

Kansas City Royals: Lorenzo Cain

The Kansas City Royals have one of the best minor league systems in baseball. They have seen many of their top prospects reach the majors this year, but there is one that is lingering in the minors.

Lorenzo Cain came over in the Zack Greinke deal. He has put up outstanding numbers in the minor leagues this year but the Royals have yet to call him up. Cain should finally get his chance in September.

Los Angeles Angels: Mike Trout

Mike Trout is one of the top prospects in baseball. The Los Angeles Angels gave him a chance to show what he could do in the majors earlier this year when Peter Bourjos was injured.

Trout struggled a bit but that should not stop the Angels from calling him up this September. He will gain valuable major league experience that should help him when he reaches the majors once again next season.

Los Angeles Dodgers: Jerry Sands

The Los Angeles Dodgers gave Jerry Sands an extended look earlier this season. He appeared in 41 games for the Dodgers, but he struggled to get on base.

Sands continued to tear up Triple-A pitching once he was sent down. The rookie will get another chance to show what he can do in the majors this September.

Milwaukee Brewers: Mat Gamel

The Milwaukee Brewers have had trouble finding a place for Mat Gamel on their major league roster. They should be looking to find a way to get his bat into the lineup.

Gamel has been mashing Triple-A pitching this year. He has hit for both power and average and looks like he is more than ready to play in the majors.

Minnesota Twins: Joe Benson

The Minnesota Twins will likely be looking for an outfielder next year since both Michael Cuddyer and Jason Kubel will be free agents after the year. They may be able to fill one of the voids internally with Joe Benson.

Benson had knee surgery which kept him out for a few weeks during the 2011 season and may have prevented him from being called up already. He has battered Double-A pitching this year.

New York Mets: Jordany Valdespin

The New York Mets have been troubled by injures all year which has allowed them to call up many of their prospects. One player who has yet to be called up to the majors is Jordany Valdespin.

He should get called up in September. Valdespin has put up impressive numbers at Double-A this season. The second baseman should be in the competition for the starting job next year, and a good September could help him.

New York Yankees: Jesus Montero

Every time he steps into the batters box, it becomes more and more apparent that the New York Yankees should not be writing Jorge Posada's name in the lineup card on a regular basis.

The Yankees even have a successor waiting in the wings. Jesus Montero will likely be called up in September, and if he has a good month, he could find himself on the Yankees playoff roster while Posada is sitting at home.

Oakland Athletics: Chris Carter

Chris Carter has missed a number of games as a result of injuries this year, and he has seen his production fall. That is one of the main reasons why Brandon Allen is in the majors and Carter is not.

Carter has been a power bat in the Oakland Athletics' farm system for years. While his power numbers have dropped this year, Carter still has a ton of potential and could eventually be the A's starting first baseman.

Philadelphia Phillies: Domonic Brown

Domonic Brown's time in the majors was limited because of injuries. When he was on the field, Brown struggled. He was sent back down to the minors after the Hunter Pence deal.

Brown should be called back up in September. If the Phillies clinch a playoff spot early in September, Brown could be playing almost every day in the Phillies' outfield.

Pittsburgh Pirates: Pedro Alvarez

Pedro Alvarez had a great season with the Pittsburgh Pirates last year. However, he struggled a lot this year and was sent down to the minors.

Alvarez has begun to find his stroke once again in the minors. He will be back up with the Pirates in September. The Pirates are hoping that he can return to the form he showed in 2010.

San Diego Padres: Anthony Rizzo

The San Diego Padres called up Anthony Rizzo earlier this season, and he struggled mightily. Rizzo should get a chance to show that he was just in the midst of a cold streak once he is recalled this September.

Rizzo has feasted on Triple-A pitching this season. He is amongst the batting average leaders in the Pacific Coast League, and he has shown a lot of power this season.

San Francisco Giants: Conor Gillaspie

Conor Gillaspie has improved his numbers while moving up a level each year since he has been in the San Francisco Giants minor league system.

The Giants gave Gillaspie a few at-bats in the majors earlier this year. With the Giants in the midst of a playoff race, Gillaspie will likely only see at-bats off of the bench, but he could be a big presence.

Seattle Mariners: Alexi Liddi

Stuck in last place in the American League West, the Seattle Mariners will definitely give a few prospects a look in September. These players could eventually help them in the future.

Given Chone Figgins struggles this year, it is surprising that the Mariners have not yet called up Alex Liddi. He has impressive power and is amongst the minor league home run leaders. Liddi does strike out a lot, so he will need to work on his plate discipline.

St. Louis Cardinals: Zack Cox

The St. Louis Cardinals are currently chasing after the Milwaukee Brewers for the NL Central crown. They will be looking forward to the help that they can bring up in September.

The Cardinals have seemingly found a third baseman in David Freese, but Zack Cox will be able to help the Cardinals by coming off of the team's bench.

Tampa Bay Rays: Alexander Torres

The Tampa Bay Rays are normally very cautious when it comes to promoting their pitching prospects. Without a chance for them to make the playoffs this season, they likely will not promote Matt Moore.

The best pitching prospect that the Rays will likely promote to the majors this September is Alexander Torres. He has pitched well in the minors this year but does have some control issues. The Rays could use him out of the bullpen.

Texas Rangers: Leonys Martin

The Texas Rangers were able to sign 23-year-old Cuban defector Leonys Martin this season. He has already reached Triple-A for the Rangers.

Martin will be able to help the Rangers this season. He should get a decent number of starts in the Rangers outfield, and he will also likely be used as a defensive replacement and as a pinch-runner.

Toronto Blue Jays: Travis Snider

Travis Snider has picked up a number of frequent flier miles this year, and he has been up and down between the Toronto Blue Jays and their Triple-A affiliate in Las Vegas.

Snider has been outstanding in the minors this year but he has not seen that success translate to the major leagues. He should get some at-bats once again in September, and they may help determine his future with the team.

Washington Nationals: Stephen Strasburg

Last season, the most anticipated debut of the year was Stephen Strasburg's first start for the Washington Nationals. This year, his first start when he returns from Tommy John surgery will be highly anticipated as well.

The pitching phenom is expected to return to the Nationals this September. Baseball fans from around the country will be excited to see how this electric pitcher performs in his return to the majors.
