31-year old righty reliever Kasey Olenberger could possibly get a call to the show when rosters expand in September if he keeps pitching like he is right now. In 39 games (1 start) in AA-ball this season, Olenberger is 7-1 with a 1.01 ERA and a 1.01 WHIP. In 53 1/3 innings in the minors this season he has only allowed 39 hits while whiffing 50 batters. Olenberger deserves a reward for a fine season and that would be a promotion to the majors at some point.

25-year old lefty swinging 1B Gaby Sanchez was the Marlins’ #8 prospect heading into this season according to Baseball America. Sanchez has played in 48 games this season in AAA-ball and he is 54 for 186 (.290 avg, .824 OPS) with 33 runs scored, 8 homers, 29 RBIs and 4 stolen bases. If Jorge Cantu is traded (a big mistake) then Sanchez would likely get the call to replace him.

According to Baseball America 22-year old righty starting pitcher Ryan Tucker is the Marlins’ #5 prospect and they will be without him for at least the next 2 months. Tucker has started 2 games in AAA-ball so far this season and he was 0-1 with a 17.36 ERA and a 3.43 WHIP. He has allowed a stunning 9 hits and walked 7 batters in only 4 2/3 innings in the minors so far this season. Tucker pitched in 13 games (6 starts) for the Marlins last season and he was 2-3 with a 8.87 ERA and a 1.86 WHIP. The Marlins will take is slow with Tucker’s rehab.

The Marlins have lost 24-year old righty reliever Scott Nestor on waivers to the Phillies. Nestor came into this season as the #25 prospect in the Marlins’ minor league system according to Baseball America but he had a awful year in 2008. Nestor pitched in 55 games (0 starts) in AAA ball this season and he was 1-1 with a 7.44 ERA and a 1.67 WHIP. He has good stuff as he whiffed 64 batters and allowed only 54 hits in 61.2 innings this season, but, he walked a stunning 49 batters.

18-year old righty swinging Matt Dominguez had a rough time last season in his first taste of professional baseball but things are going a lot better this year. Dominguez has played in 43 games in A-Ball this season and he is 47 for 161 (.292 avg, .781 OPS) with 27 runs scored, 5 homers and 23 RBIs. The Marlins can afford not to rush Dominguez so that he’s ready to stay with them a long time when he finally makes it to the show.
