Here's some Sanchez stats, per Baseball-reference.com:
.300 hitter who doesn't walk
No power with 37 HRs in four and a half full seasons.
Below average fielder.
Alderson was 6-1 with a 3.47 ERA in AA. The only thing I can think of is he's not a strikeout pitcher, but I'm grasping at straws here.
A mere three hours ago, Baggs posted this on his blog regarding the deal:
"Names such as John Bowker, Kevin Frandsen and Jesus Guzman have been bandied about by si.com as guys who might be going the other way."I would give up ALL of those guys for Sanchez if I could keep Alderson. I don't get it!
