Dodgers optioned RHPs Chris Withrow, Josh Wall and Stephen Fife, LHP Michael Antonini and OFs Alfredo Silverio, Scott Van Slyke, Alex Castellanos to minor league camp. The Dodgers also reassigned right-hander Shane Lindsay and infielder Russ Mitchell to minor league camp. Withrow, a 2007 first-round pick, fanned 130 batters over 128 2/3 innings last season, but has spent three straight years at the Double-A level and continues to have issues with his control and command. Silverio, who was recently ranked as the organization's No. 4 prospect by Baseball America, is sidelined indefinitely after being involved in a serious automobile accident in his native Dominican Republic in late-January.
