As you know, the A’s have the 12th overall pick in the June draft. Jim Callis’ always-informative Ask BA segment in the latest Baseball America print magazine (issue 0809) discusses some possibilities.
Callis suggests shortstop Gordon Beckham would make sense if available – he’s likely to wind up somewhere in the infield long-term. Callis also rattles off a couple of catchers (Kyle Skipworth and Buster Posey), pitcher Christian Friedrich, and outfielder Aaron Hicks. Friedrich may be a consideration for the Giants at #5, however.
