OAKLAND, Calif. (AP) - Matt Chapman hit a tiebreaking three-run homer off Jeremy Hellickson in a five-run fourth inning, and the Oakland Athletics overcame an early two-run deficit to beat the Baltimore Orioles 9-3 on Sunday.
Matt Joyce and Matt Olson also homered as the A's gained a four-game split.
In his worst outing since Baltimore acquired him from Philadelphia last month, Hellickson (1-2) gave up six runs - twice as many as he allowed in his previous two starts. He allowed five hits in five-plus innings.
Manny Machado hit his 22nd homer and scored twice for Baltimore.
Kendall Graveman (3-3) had an uneven outing in his first win since returning Aug. 3 from a disabled list stint caused by a strained right shoulder. He matched his career high of eight strikeouts, allowing two runs and eight hits in seven innings.
