Oakland, CA (Sports Network) - Josh Donaldson hit a game-tying two-run homer and then the game-winning RBI single in the bottom of the 11th inning, lifting Oakland to a 3-2 victory over Boston in the finale of a three-game set.
Matt Thornton (0-4) walked pinch-hitter Chris Young to start the frame, and Eric Sogard sacrificed him to second. Coco Crisp's grounder failed to move him, then Derek Norris drew a pinch-hit base on balls ahead of Donaldson's solid hit to center to end the contest.
Ryan Cook (2-2) turned in two scoreless relief innings to pick up the win for the Athletics, who hit the All-Star break having won seven of their last 10 and hold a two-game edge over Texas in the AL West.
Dustin Pedroia and Brock Holt knocked in a run apiece for the Red Sox, who dropped the final two games in the series but still hold a 2 1/2-game edge in the AL East over Tampa Bay.
