Matthew Pouliot breaks down the top prosepects for each team in the NL West. Here's a link to the Giants Prospect page: Rotoworld Giants Prospect Breakdown
#1 is, obviously, Villalona. Money line:"He doesn't take wild swings at breaking balls, and he shows some willingness to take pitches the other way."
A disciplined hitter? In the Giants farm system?
#2-4 are Sosa, Alderson, Bumgarner, followed by Noonan and Schierholtz.
For some reason Velez is number seven even though he's with the big club. If you take him out Tanner would be #10.
