OAKLAND (AP) Mike Fiers pitched three-hit ball into the seventh inning and the Oakland Athletics took advantage of Baltimore's shoddy defense to beat the Orioles 3-2 Monday night.
Fiers (7-3) allowed two unearned runs over 6 2/3 innings, getting into the seventh for the seventh time in eight starts - a stretch that started with his no-hitter May 7 against Cincinnati. He struck out four and walked two.
Oakland took a 3-2 lead in the second on catcher Chance Sisco's two-run throwing error. The A's loaded the bases with no outs when Josh Phegley was hit by a pitch, Marcus Semien walked and Matt Chapman reached on an infield hit. Shortstop Jonathan Villar then fielded Matt Olson's grounder and got the force at home on Phegley, but Sisco threw wide of first trying for a double play, allowing Semien and Chapman to score.
Chapman was initially called out at home after first baseman Chris Davis retrieved the ball and whipped it home, but the call was reversed on replay, showing Chapman slid under Sisco's tag.
Orioles starter Andrew Cashner (6-3) gave up three runs - one earned - in six innings of four-hit ball.
Semien extended his hitting streak to 14 games for Oakland. He doubled leading off the first and scored on Olson's double one out later.
The last-place Orioles suffered their sixth straight loss.
