Middlebrooks to have MRI on calf; Carp able to play

BOSTON -- Shortly before Saturday night's game, the Red Sox announced that Mike Carp, who had been in the lineup playing first base, batting fifth, was scratched because of tightness in his lower back. A few minutes later, third baseman Will Middlebrooks was scratched with what was called a right calf cramp.

While Carp was ultimately able to play, entering the game in the 10th inning, Middlebrooks' injury may be more serious.

Middlebrooks is scheduled to undergo an MRI on Sunday morning for what manager John Farrell called a right calf strain.

Farrell said Carp's back tightened up during batting practice and Middlebrooks felt his injury during pregame sprints.
