Victorino tweaks hamstring, day to day

CHICAGO -- Two months into what is supposed to be a three-year tour of duty in Boston, the last thing Shane Victorino wants is to become known as the Limpin’ Hawaiian.

But Victorino, who has been tormented by back problems that caused him to miss seven games altogether and come out of several others early, was forced to leave Monday night’s game when he felt his left hamstring grab in the sixth inning while running the bases.

Victorino had just beaten out an infield hit with two out in the sixth and was sprinting from first to third on Dustin Pedroia’s drive to center field that was caught on the track when he felt the muscle grab.

“I tried to keep running,’’ he said, “but I didn’t have the strength I usually have there.’’

Victorino actually returned to his position in right field at the end of the at-bat, but gave in to prudence, trotting back into the dugout.

Daniel Nava finished the game in right field, while Jonny Gomes took over for Nava in left.

“Frustrating,’’ Victorino said. “I want answers why. I don’t know if it’s all connected, but I just want answers.’’

Manager John Farrell said Victorino is day to day. Victorino said he’d have to wait and see how he feels before deciding whether to give it a go Tuesday night. With leadoff man Jacoby Ellsbury in a prolonged slump (3-for-24 on the current road trip, including four ground balls to second base Monday), the Sox can ill afford to lose Victorino at the top of the order.
