Pedroia, Boston's invaluable second baseman, injured his right hamstring after a two-run single in the bottom of the sixth that gave the Red Sox the lead in a game they won, 5-1, against the Orioles, on Wednesday night. Pedroia underwent advanced imaging after the game, and the club is awaiting the results.
After rounding first, Pedroia grabbed his hamstring and limped back to the bag.
"Yeah, you know, he lost his footing going around the bag," said Red Sox manager John Farrell. "He slips with his left foot and when he tried to plant and brace himself with his right foot, the ground gave out or he stepped in a little bit of a hole and wasn't able to keep solid footing. That's where he felt it in the hamstring. Any time a player comes off the field, you're concerned."
Ramirez suffered a left hand contusion when he was struck on a line drive by teammate Xander Bogaerts an inning earlier.
"It's always good to win, but when you lose two guys, it's tough," said right-hander Clay Buchholz. "Those are two guys that are in the middle of our lineup. Hopefully it's just a little scare and nothing is really bad wrong with them, and we'll get them back out there and get them on the field."
