When the Phillies' aces are talked about, usually the names Halladay, Lee and Hamels are brought up, but in Clearwater, a new batch of aces have popped up. The 'Baby Aces', a nickname given to the best pitching prospects in the system, have proven that they are nothing to overlook. The group consists of righthanders Brody Colvin (20) and Trevor May (21), and lefthanders Julio Rodriguez (20) and Jon Pettibone (21) (the group did have a fifth ace, Jarred Cosart, who was part of the Hunter Pence trade). At the FSL All-Star Game, the Baby Aces (minus Colvin) were perfect, each throwing a hitless inning. The star of the group, at least so far this season, has been Julio Rodriguez, who picked up his Minors' best 15th win last night, allowing three runs on two hits and striking out seven over five innings. Rodriguez, who has won his last seven starts and hasn't lost a game since June 29, has a record of 15-6 this season, with a 3.13 ERA and 126 Ks in 126.2 innings. A close second is Trevor May, who has already the Threshers' single season strikeout record (story here) with more than a month to go in the season. May has struck out 10 or more batters in six of his 22 starts, and his season total sits at 169 in only 124.1 innings pitched, giving him a Randy Johnson-esk K/9 ratio of 12.23, better than any of the Phillies' Aces. His record currently stands at 8-6, and he has a 3.60 ERA.Unfortunately though, not all the Baby Aces have had a great year. Jon Pettibone (8-9), started the year off strong, coming into the all-star break with a 6-4 record and a 2.47 ERA. But, post all-star game Pettibone struggled, collecting a 2-5 record with a 3.90 ERA. Pettibone is a solid pitcher, his 1.19 WHIP proves that, and with time the 21 year old will mature into a decent starting pitcher.And then there's Brody Colvin. His 2-6 record and 4.25 ERA do not reflect the kind of potential this guy has. Coming off of a back injury earlier this year, his numbers may be affected by pain that he still has. Being young, though, he can hopefully pull through and improve as time goes on.
