Fortunately for the Red Sox, the ailment is not considered serious. In fact, Red Sox manager Terry Francona said that Pedroia would sit out Tuesday's game in Anaheim only as a precaution and probably be right back in the lineup on Wednesday.
"You know if he comes out, he's hurt because he's a tough kid," Francona said. "He also thinks he can play Tuesday. I don't think that I would do that, just because we're going to travel out there, but I bet he'll be in there Wednesday. I think that's very realistic. Certainly, we're going to reevaluate him [Monday], but I think [team medical director] Tom Gill and everybody think we're OK with that."
Pedroia said that the injury has been bothering him for about a week and he tweaked it during his second at-bat on Sunday.
"I just took a swing, and my cleat kind of got stuck in the ground," Pedroia said. "It hurt pretty good. A day off tomorrow will be nice, and I already talked to Tito. He won't let me play on it Tuesday. Then we'll go from there. I'll be out there as soon as I can."
The Red Sox moved Julio Lugo into the game at shortstop to take Pedroia's No. 2 slot in the batting order. Nick Green moved from shortstop to second base. Before leaving, Pedroia went 0-for-2.
Pedroia has been on fire of late. Entering the game, he was hitting .432 in his past nine games, including two doubles, five RBIs and 12 runs.
Overall, he is hitting .320 with one homer and 12 RBIs.
First baseman Kevin Youkilis has missed the past six games with soreness in his left side. Center fielder Jacoby Ellsbury was out for a couple of games earlier in the week with tightness in his right hamstring. David Ortiz missed Thursday's game with a stiff neck. Shortstop Jed Lowrie is out until at least June as he recovers from left wrist surgery. Right fielder J.D. Drew was out of the lineup on Saturday because of left quad woes.
