"You know, he's moving decent in the outfield, he's doing everything he can," Red Sox manager Bobby Valentine said. "I mean, he's a trooper. We knew we needed him and we were short and he kept going out there. It just got to a point where it was really adversely affecting his swing."
Sweeney got a cortisone shot to alleviate the pain, but that also means he needs to stay off his foot for a few days.
"It's just one of those things where I'm not even able to run for like a week or something like that," Sweeney said. "We really don't have enough players right now to be doing that because [Daniel] Nava had a cortisone shot, too. I guess I was just an odd-man out."
Sweeney, who is hitting .292 with no homers and 13 RBIs, didn't dispute that the injury might have been affecting his performance.
"Basically, I have bone on bone, or something like that," Sweeney said. "And it's on my back foot when I swing, I'm kind of just out in front of everything right now because I can't really sit on my back side."I try not to think about it when I'm out there. It hurts after I get done running. I'd like to say that it didn't affect me. I've gotten lucky because I haven't gotten a lot of balls the last couple days. But playing center field, you cover a lot of ground, you've got to try to get what you can. I'm just kind of limited."
