The thought was that if one team outscored the other 28-13 in the first three games of this four-game series it would be the Detroit Tigers putting the hurt on the slumping A's.

It hasn't worked out that way. A's hitters beat up 11-game winner Doug Fister for 13 hits and seven runs in five innings Wednesday night en route to a 14-4 blowout win that has the A's on the verge of a four-game sweep.

Leading the way for Oakland was first baseman-turned-right fielder Brandon Moss. He delivered four hits including his 24th and 25th homers and drove in a career-best six runs. As a whole the A's had a season-best 21 hits and their 14 runs tied the season high.

Josh Donaldson Jed Lowrie Alberto Callaspo and Kurt Suzuki all had three hits for the A's who had seven players with multiple hits all by the sixth inning.

For all of that largess an Oakland sweep is still a long way off. The A's go against baseball's hottest starter the Tigers' Max Scherzer and his 19-1 record in Thursday's series finale. Bartolo Colon will pitch for the A's after spending two weeks on the disabled list because of a groin injury.

So dominant was the A's offense in this one that seven different Oakland batters had multiple hits by the end of the sixth inning. The A's scored three times on five consecutive hits in the second inning then effectively drove Fister from the game in the fifth inning with four more runs and six more hits.

Oakland came into the series having lost four of five and seven of its last 11 games The A's were pitching well enough but their defense was shaky and Congress had a better chance of getting something done than the A's did of putting a bunch of hits together.

And they particularly had trouble when Dan Straily was their starting pitcher. They'd scored just six runs in seven games since the All-Star break on Straily's behalf one reason he'd come into the game with a seven-game losing streak.

The three runs on consecutive singles by Yoenis Cespedes Daric Barton Callaspo Eric Sogard and Suzuki in the second gave him an early cushion. Torii Hunter homered for the Tigers in the third but while Straily put men on base with regularity that was all Detroit got.

Oakland scored four times in the fifth with Fister still in the game then three times in the sixth and four times in the eighth against the bullpen. Moss hit his first homer a two-run shot in the sixth and his second was a three-run bomb in the eighth.

Straily wound up throwing six innings and allowed just the one run despite giving up eight hits and two walks.
