Keith Law summarized the draft for every MLB team. Here's what he said about the Phils.
Summary: The Phillies went after -- wait for it -- upside. Shane Watson (1) has one of the better curveballs in the class and sits in the low 90s, although there's some stiffness to him that reminded me a little of Joe Blanton. Mitch Gueller (1) was a two-way player in high school, a good athlete who would sit 91-93 and has a chance for three average or better pitches. Dylan Cozens (2) is quite a story, a football/baseball guy who was kicked off one high school team after a physical altercation with his coach; he's an athletic left-handed hitter who probably wouldn't have made my own top 200. Alec Rash (3) is up to 95 with a good body and delivery, and a very fresh arm as an Iowa kid without many innings behind him. Zach Green (4) isn't a shortstop long term, but if you buy the bat, you might see a third baseman with some pop. Kevin Brady (10) would have gone higher had he not missed May with a hamstring strain; before that he was 90-94 with some downhill plane and a big, durable body.
And where does the top pick Mitch Gueller rank amongst the team's current prospects?
Third, behind Trevor May and Jesse Biddle. There's a big drop off after these three guys at the moment, although I am looking forward to seeing what Larry Green, their top pick last year, does in live games later this month.
