Entering tonight, the Red Sox were the only team in the majors that had not blown a save this season. They were a perfect 9 for 9. No more. Jonathan Papelbon, on for the ninth, just served up a two-run homer to Travis Buck, tying the game 4-4. Bobby Crosby, who started the inning with a single to left, came around to score on Buck’s blast, which found the seats in the right field grandstand. Papelbon had been 8 for 8 this season before that.
