Overall, the 2012 draft class is heavy on high school pitchers and power bats.  The growth of those two areas will dictate the depth the draft can provide and there are plenty of at-bats and innings for these kids to improve.

1. Lucas Giolito – RHP, Harvard-Westlake HS (Studio City, CA)
Workhorse top of rotation frame, three plus pitch potential, should be fast moving prospect

2. Mark Appel – RHP, Stanford University
