"Milton Bradley's broken-bat, two-run single in the fifth brought Seattle even and Franklin Gutierrez's splintering single an inning later gave the Mariners the lead for good in a 4-2 win over the Oakland Athletics on Wednesday night.

Jason Vargas (1-1) pitched six innings for Seattle, following up on eight shutout innings from Doug Fister a night earlier, as the back of the rotation came through to give Seattle its first series victory of the season.

Down 2-0 in the fifth, Bradley dumped the first pitch from Oakland starter Gio Gonzalez into left field, sending his bat barrel nearly to third base. The hit scored two and Gutierrez's hit an inning later scored Adam Moore with the go-ahead run.

Seattle reliever Brandon League worked a scoreless seventh and eighth innings and David Aardsma converted his fourth save - he's closed all of Seattle's wins - with a perfect ninth. Aardsma has converted 14 straight saves since last August. Bradley, with his eighth big league team, finally made a mark with the Mariners on Tuesday night with a game-winning three-run homer in the eighth inning. But he was drawing the ire of fans after just one at-bat on Wednesday.

Bradley rounded third too far after Moore's infield hit in the second and was tagged out during a rundown between third and home for the Mariners' second base-running blunder of the inning.

He was hearing the cheers again a few innings later. Seattle loaded the bases on an infield single by Ichiro Suzuki and walks to Chone Figgins and Gutierrez with one-out in the fifth. Jose Lopez fouled out behind third, but Bradley muscled Gonzalez's first offering into left."
