"He's good," said Red Sox manager Terry Francona. "The X-ray is fine, which we kind of thought, but [we did it] just to be careful."
The surest sign that Pedroia was as good as the X-rays said was that he was already lobbying Francona to be back in the lineup for Thursday's home game against the Marlins.
"I think what we'll do is let him take BP tomorrow and play him [Friday]," Francona said. "He's OK. There's no swelling. Actually, he's a little bit sore higher, which is real good. He got a clean bill of health."
The injury was sustained Tuesday night, when Pedroia dove awkwardly for a ground ball by Twins leadoff man Denard Span in the bottom of the first inning. Pedroia made a throwing error on the play.
Naturally, the Red Sox held their breath just a bit right after the play happened.
"Every time you see him dive -- we've seen him come up a number of times on that shoulder," Francona said. "But you know what? There's nothing you can do. You've got to play the game. I don't know how else to get around it. It was a great play. You've just got to play the game. Again, I don't think anybody thought there was something there, but it's nice to hear that."
Pedroia was the American League's Most Valuable Player Award winner in 2008. Last year, he hit .296 with 115 runs, 48 doubles, 15 homers, 72 RBIs and 20 stolen bases.
Pedroia went 0-for-1 on Tuesday. For the spring, he is hitting .351 (13-for-37) with one homer and eight RBIs.
The Red Sox took on the Pirates on Wednesday, a game Pedroia wasn't scheduled to play anyway because he is filming a commercial. Tug Hulett started at second base for Boston.
