OAKLAND -- Jed Lowrie hit a bases-loaded, bases-clearing double in the decisive sixth, Mark Cahna added a solo homer that inning, and the Oakland Athletics rallied to beat the San Diego Padres 6-2 on Tuesday night.
Chad Pinder added a solo homer in the seventh.
The A's finally got to San Diego starter Clayton Richard (7-8) in the sixth.
Pinder walked to start the sixth as the first five hitters reached base. Khris Davis followed Lowrie's double with a run-scoring single before Cahna's 11th home run, after a double play.
Emilio Pagan (2-0) pitched 1 1/3 innings for the win in relief of A's starter Chris Bassitt.
A's third baseman Matt Chapman returned from the disabled list after missing 16 games with a recurring right hand injury that began bothering him during the offseason. He had played in 149 straight games before the DL stint.
Wil Myers hit a run-scoring double in the fifth right after Eric Hosmer's RBI groundout got the Padres on the board.
Bassitt, who has just one win in five starts since being called up last month, escaped jams in the first and third innings as the Padres stranded five baserunners. The A's made a pair of forceouts at home in the third, including first baseman Matt Olson's nifty throw after a backhanded stop.
Myers' double chased Bassitt. He allowed two runs on seven hits in 4 2/3 innings, struck out six and walked three.
Richard gave up five runs and six hits, walked a season-high five batters over six innings and struck out two in his second straight defeat.
Oakland, which had its six-game winning streak snapped Sunday by Cleveland, won for the 13th time in 16 games despite grounding into five double plays.
Leadoff hitter Travis Jankowski had three hits for San Diego, which will conclude the short two-game series Wednesday having played 23 of its last 28 away from Petco Park.
The A's improved to 6-2 in interleague play.
