OAKLAND, Calif. -- Coco Crisp homered among three hits and A.J. Griffin worked seven strong innings as host Oakland beat up on Boston again, 7-1, en route to its eighth straight victory on Saturday night.

Brandon Inge added a two-run double and Derek Norris drove in a pair of runs for the Athletics, who maintained the top spot in the American League wild card race. Oakland, which beat the Red Sox 20-2 on Friday, is two games ahead of the second-place Baltimore Orioles and 3 1/2 games clear of the Tampa Bay Rays.

The A's got three home runs and 13 RBIs from former Boston players in Friday's drubbing and Crisp, who was the only Oakland player not to record a hit in that game, finally got to his former team in the bottom of the first on Saturday. Crisp sent a leadoff home run out to left-center and added a stolen base while finishing a triple shy of the cycle.

Griffin (4-0) was perfect through 4 2/3 innings until Jarrod Saltalamacchia bunted against the shift, sending an infield single towards the vacated third base position. Griffin, who was activated off the disabled list to make the start, ended up yielding one run on three hits while striking out five.

Felix Doubront (10-7) lasted only three innings for the Red Sox. Oakland exploded for four runs in the third off the left-hander, with Yoenis Cespedes and Norris sandwiching RBI singles around Inge's two-run double.

Dustin Pedroia drove in the lone run for Boston, which has dropped five straight.
