Trevor May is now the top prospect in the Phillies' system.
After the Phillies traded away Jarred Cosart and Jonathan Singleton in July to get Hunter Pence and Dom Brown used up his rookie eligibility, the top prospect in the Phillies' system is pitcher Trevor May. May passed out some of the other pitching prospects after a big year in High-A ball last year. May struck out 208 hitters over 151 innings last year and projects as a middle of the rotation starter.
The Phillies system is a bit weaker in positional players at the moment. The top hitter in the system is catcher Sebastian Valle, a potential starter that will begin in Double-A this year. Freddy Galvis is a glove-first prospect that could eventually take over for Jimmy Rollins at shortstop. Outfielder Jiwan James and third baseman Maikel Franco are high-upside guys, but each have significant risk.
The Phillies drafted some high upside players last June worth mentioning. The top prospect from that group right now is power hitting outfielder Larry Greene, though he was a high school player that will take plenty of time to develop. Roman Quinn has a bunch of tools but is a bit raw. Shortstops Tyler Greene and Mitchell Walding are also worth a mention.
May is the top pitcher in the system, but that could change next year because he has some competition. Jesse Biddle, the team's first round pick in 2010, could break out this year in High-A. Brody Colvin will head up to Double-A this year and is a player with the potential to emerge this year. Jon Pettibone is another starter that will reach Double-A with May and Colvin this year and could be a middle of the rotation starter.
The Phillies also have some high upside relievers. Phillippe Aumont is a potential closer or setup man down the road, and could debut this year. Justin De Fratus is a potential setup man that is expected to begin the year in the big leagues after debuting last year.
This doesn't even get into the likes of pitchers Lisalberto Bonilla, Julio Rodriguez, Perci Garner, Austin Hyatt, Joe Savery, Michael Schwimer and Austin Wright and hitters Aaron Altherr, Kelly Dugan and Gauntlett Eldemire. All of those guys would be receiving more attention in another system, but the Phillies' system is just that deep.
The Phillies have dealt away so many top prospects over the last few years. In addition to Cosart and Singleton, the team has dealt away Anthony Gose, Kyle Drabek, Michael Taylor and Travis D'arnaud. Still because of the depth of the high ceiling prospects in the system the team has a solid farm system despite lacking some of the top level prospects it usually has.
