Dodgers C Martin out 4-6 weeks

The injury will sideline Martin for the remainder of Spring Training and Opening Day. Dodgers manager Joe Torre said that rookie A.J. Ellis will get the majority of work with Martin out. Brad Ausmus, 40, is the backup catcher.

Martin apparently suffered the injury during a base-running drill earlier in the week. He then aggravated the groin when he stole a base in Friday's game.

The two-time All-Star had an MRI on Saturday, which confirmed the injury. Martin will be sent to Los Angeles for further medical exams.

In 143 games last year, Martin batted .250 with 53 RBI and seven homers.
