Smilin' Ken Rosenthal has a name for us (unconfirmed) to round out the second prospect (if Happ doesn't count as a prospect anymore):
SS Jonathan Villar.
Villar is a 19-year old shortsop for Single-A Lakewood, hitting .272/.332/.358 in 100 games this season, with 103K:26BB and 38SB. He has committed 42 errors in 99 games for a .913 Fld%
In other words, he's a worse-fielding, slightly-better hitting, faster Jiovanni Mier.
