Red Sox left-hander Jon Lester will miss his next start with a strained lat muscle. Lester left Tuesday night's game against the Blue Jays after the fourth inning despite having a no-hitter intact. "He won't pitch Sunday. I think that's a foregone conclusion," Boston manager Terry Francona said. "I think the next decision is whether we DL him. We were probably going to have him come out last anyway out of the (All-Star) break just because we wanted to build in a break for him. If we're going to have him miss 10, 11, 12 days, another three might not be (a bad idea)."
