10/20 AFL update
Starlin Castro shifted over to second base Monday for the Mesa Solar Sox, and went 1-for-4 in a 8-1 loss to the Peoria Javelinas in Arizona Fall League play. Castro has played shortstop in the Cubs’ Minor League system. Maybe the Cubs are considering him for 2010 at second? Mesa third baseman Josh Vitters, the Cubs’ No. 1 Draft pick in 2007, was 0-for-4.
