Playing in Bill Murray’s hometown, Shane Victorino starred in his own version of “Groundhog Day.” Victorino left in the sixth inning of the Red Sox' 6-4 loss here Monday night after experiencing tightness in his left hamstring. It marked the fifth time this season that Victorino has exited a game early because of an injury. “It seems like if it ain’t one thing, it’s another right now,” Victorino said. “They say it’s all connected. That’s what’s frustrating for me. What is it? I just want to get back to being healthy and being out there and being a healthy player and feeling good.” Victorino missed a week in April because of tightness in his lower back and didn’t play in two games last week after the injury recurred. After legging out an infield single in the sixth inning last night, he felt “a little something grab” in his hamstring when he tried to run from first to third on Dustin Pedroia’s two-out fly ball to center. After Victorino trotted out to right field for the bottom of the sixth, manager John Farrell ran out of the dugout to check on him, at which point the decision was made to remove him from the game. Victorino will be reevaluated today. “Given what he’s been dealing with, low back,” Farrell said, “I wasn’t going to take any chances in that situation.” Said Victorino: “I don’t think this is anything serious, nor do the trainers. But I don’t want to make it worse and miss a lot of time for no reason.”
