White Sox general manager Rick Hahn believes Matt Davidson is still improving defensively. Hahn acquired Davidson from the Diamondbacks for closer Addison Reed on Monday with the intention of making him Chicago's everyday third baseman. "Solid actions, strong arms, good hands," Hahn said. "The question you'll hear from time to time with scouts and has been written about publicly is about the lateral movement. We think it has improved. We think it's going to continue to improve. We see him over there for the long term once the development is finished." Davidson, the 35th overall pick in the 2009 MLB Amateur Draft, slashed .280/.350/.481 with 17 home runs, 32 doubles and 74 RBI in 115 games this past season at Triple-A Reno.
