Oakland, CA (Best E Casino) - Carlos Gonzalez belted a three-run double to spark a six-run seventh inning, as the Oakland Athletics beat Detroit, 10-2, to complete a three-game sweep.

Bobby Crosby had two hits and two runs batted in, and Travis Buck homered and scored twice for Oakland, which is riding a four-game winning streak after dropping four straight.

"That feels great," Gonzalez said. "It was my first hit in the series too. I was waiting for that pitch because they stayed away from me the whole series. I faced a lot of lefties and they were throwing me a lot of sliders so I made good contact going the other way. I got the big hit at the end."

Justin Duchscherer (5-4) allowed only two baserunners over the first five innings including a stretch that saw him retire nine straight and 12 of 13 batters for the win. His outing was finished after 6 2/3 innings, giving up two runs on three hits and five walks after running into trouble in the later innings.

Tigers starter Nate Robertson (3-6) surrendered five runs on eight hits and three walks while striking out five through 6 1/3 innings in taking the loss.

Magglio Ordonez and Carlos Guillen knocked in the runs for Detroit, which finished 3-6 on its road trip.

"He (Robertson) was OK today," Tigers manager Jim Leyland said. "He certainly wasn't bad. We've been getting enough out of our starters to give us a chance to win games but our offense basically has stunk. I'm sorry but that's just the way it is. I'm befuddled by it, but I'm not upset about it. I've talked about it long enough. Our offense basically has stunk and it hasn't really gotten into gear on any consistent basis the entire season. I can't hide those facts and I'm not going to."

The Athletics got to Robertson in the fourth for the first run of the game. Emil Brown and Daric Barton started the frame with singles, and Brown scored on Buck's double-play groundout.

Oakland padded its lead one inning later. Jack Hannahan worked a one-out walk and Jack Cust roped a two-out double to right two batters later. Crosby then smacked a double to left, plating both runners.

Detroit had back-to-back one-out walks in the sixth and Guillen put the Tigers on the board with a single up the middle. Marcus Thames then worked a walk to load the bases and Duchscherer hit Ordonez with a pitch, forcing in a run. Duchscherer induced Jeff Larish into an inning-ending double play to stop the bleeding.

Buck gave Oakland back a two-run cushion, leading off the home half with a blast to right-center.

The A's batted around for six runs in the seventh, breaking open an otherwise close game. Robertson started the inning, but was removed in favor of Freddy Dolsi after walking a batter and recording an out. Dolsi struck out the first batter he faced, Crosby, and issued a walk to Brown before giving way to Casey Fossum.

Barton ripped an RBI single and Buck singled to load the bases before Gonzalez doubled to left, clearing the bases. Rob Bowen then singled back up the middle to plate Gonzalez. Aquilino Lopez came on for Fossum and gave up a Hannahan double to right-center that scored Bowen and capped the scoring.
