The Boston Red Sox lost this one on a botched bunt that turned into a costly double play.
Two base running blunders in the top of the ninth kept the Red Sox from adding on against the Athletics, who rallied in the bottom half and won on Coco Crisp's game-ending sacrifice fly in Oakland's 3-2 victory Tuesday night.
Nick Punto popped up his bunt, first baseman Chris Carter charged in to make a diving catch and threw out Mike Aviles in a close play by covering second baseman Jemile Weeks. Then, Ryan Kalish was caught stealing going for third.
''First and second, no outs in the top of the ninth, that's where the game was lost,'' manager Bobby Valentine said. ''You can't bunt into a double play.''
The A's got singles from Carter and Cliff Pennington before pinch-hitter Brandon Moss' tying single against Alfredo Aceves (0-6). Then Crisp delivered his third career walkoff RBI and Oakland's first game-ending sacrifice fly since Dan Johnson had one May 15, 2007, against Kansas City.
