Dustin Pedroia out; Jed Lowrie at 2B

BOSTON -- Only two games into his return to the Red Sox, second baseman Dustin Pedroia was scratched from Thursday's lineup because of soreness in his fractured left foot, raising questions about just how much he will be able to play for the balance of the season.

Pedroia said the foot felt "terrible" after Wednesday's game, one in which he walked, stole second and scored a run; singled; and dropped a sacrifice bunt. "I didn't sleep very well," he said.

He still came to the ballpark on Thursday hopeful of playing against the Los Angeles Angels, and manager Terry Francona had him batting second and playing second on the lineup card posted in the Sox clubhouse.

But Pedroia said that while running the bases during batting practice, he experienced continuing discomfort, and the decision was made to replace him with Jed Lowrie.

Pedroia said doctors had told him to expect periodic soreness.

"I went from playing two games in Pawtucket, two games in this environment, obviously my foot's sore," he said. "It's tough after the game. Hopefully I wake up tomorrow and move around a lot better.

"They told me it's kind of impossible to break your foot in the area I broke it and come back and play 43 straight games. I mean, I knew that," he said.

The 2008 AL MVP missed 44 games after he was placed on the disabled list on June 26 with a broken bone in his foot.

Pedroia said he'd have to see how the foot feels before saying whether he'll be able to play Friday night here against Toronto.

"They kind of won't let me go out there if it's hurting," he said. "Today it's pretty sore in the area I broke it. That's when you kind of got to take a step back, get treatment and hope it's better tomorrow."

Pedroia said that stealing second (he continued to third on a throwing error) "probably wasn't the smartest idea on my part." A moment later, he had an even blunter assessment, calling it "stupid."

"That's part of my problem, always diving all over the place. I've got to be smart about everything. ... I think we're at the point now it's not all the way healed. I'm going to have days like this where it feels terrible."
