The Boston Red Sox fell to 1-3 on their current road trip with a 5-4 loss to the San Francisco Giants Friday night. Tim Wakefield took the loss dropping him to 2-6 on the season. Dustin Pedroia left the game in the third inning after fouling a ball off his left foot. X-rays on Pedroia’s foot were negative however, the second baseman had a difficult time putting weight on his injured foot. Pedroia will undergo further tests Saturday and Terry Francona says there is no immediate timetable for his return.
