BOSTON -- The Red Sox had rested Rocco Baldelli for the past several days because of soreness in his legs. After just one at-bat on Monday morning, Baldelli was sore again.

Legging out a three-base error when Nick Markakis dropped his fly ball to deep right in the bottom of the third, Baldelli was removed from the game in the top of the fourth with a mild left hamstring strain.

His status is day-to-day. Baldelli was replaced by Chris Carter instead of J.D. Drew, Boston's primary right fielder.

"He's sore," said Red Sox manager Terry Francona. "We'll know more [Tuesday]. It had been bothering him this week and he got the point where he really felt pretty good today. Then, when he was going around second, it grabbed him a little bit. We're going to need to re-evaluate him in the morning and see how that goes."

Baldelli's main job for the Red Sox is to start against left-handed pitchers. Francona said before Monday's game that he was hopeful Baldelli could play Wednesday night against Twins southpaw Francisco Liriano.

But Baldelli's hamstring injury will likely change those plans.

Before Monday, Baldelli last played for the Red Sox on April 13.

Baldelli's current injury does not appear to be related to chanelopathy, an ailment that causes excessive muscle fatigue and limited the outfielder to 28 games last season.
