The Red Sox rested second baseman Dustin Pedroia on Thursday night because of soreness in his fractured left foot. His absence raised questions about how ready he is to return and how much he'll be able to play the remainder of the season. Pedroia said the foot felt "terrible" after Wednesday's game. "I didn't sleep very well," he admitted. He said that while running the bases during batting practice, he experienced continuing discomfort. Doctors told him to expect periodic soreness in the foot. "I went from playing two games in Pawtucket, two games in this environment, obviously my foot's sore," Pedroia 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.
