BOSTON -- Booed off the field as he made yet another trip to the pitchers' mound, Bobby Valentine searched for something encouraging to take out of Boston's fifth consecutive loss.
"I think we've hit bottom," the new Red Sox manager said after his bullpen blew a nine-run lead, allowing back-to-back seven-run innings to hand the New York Yankees a 15-9 victory. "If this isn't bottom, we need to find some new ends of the earth."
Nick Swisher hit a grand slam in the seventh to help the Yankees erase a 9-0 deficit, then he added a two-run double in the eighth to give them the lead. Mark Teixeira had six RBIs, homering from both sides of the plate for the 13th time in his career.
"That was pretty cool," Teixeira said. "I've played a lot of games, and that may be the most fun regular-season game I've ever been a part of."
A day after Red Sox starter Clay Buchholz gave up five homers and the Yankees spoiled Fenway Park's 100th anniversary party, Boston chased New York starter Freddy Garcia after 1 2/3 innings and opened a 9-0 lead through five. But Teixeira homered twice, the second a three-run shot in the seven-run seventh that cut the deficit to 9-8.
Swisher, who also had six RBIs, hit a two-run double off the center field wall in the eighth to make it 10-9. The Yankees added five more as Valentine used three pitchers -- including closer Alfredo Aceves (0-1), who allowed five runs and failed to record an out -- to get out of the inning.
