OAKLAND -- Matt Chapman lined a three-run homer just over the left-field wall to cap a five-run fourth inning and lead the A's to a 9-3 win over the Orioles on Sunday afternoon at the Coliseum.
Down by two entering the fourth, Oakland tied the game when Ryon Healy hit an RBI double and Khris Davis beat Chris Davis' throw home on a Matt Olson grounder. Chapman then hooked a low changeup just over the 330-foot marker in left field, giving the A's the lead with his eighth homer of the year.
