Entering the game, the Red Sox were 1-27 when trailing after seven. It is the first sweep of the season for Boston, and the comeback came against an Oakland bullpen that has struggled this season.
The A's scored three in the second and one in the fourth against Clay Buchholz and were in complete command until the stunning penultimate frame.
After five straight solid starts, Buchholz labored, throwing 102 pitches over 4 2/3 innings and allowing 10 hits and four runs. Kendall Graveman fired seven strong innings (plus one batter in the eighth), retiring 13 straight at one point while giving up six hits and a run.
