OAKLAND — George Springer hit his 20th home run, Jake Marisnick and Derek Fisher also went deep and the Houston Astros beat the Oakland Athletics 4-1 on Monday night.

Evan Gattis and Alex Bregman both doubled twice to help the Astros improve to a major league-best 24-8 on the road while winning their seventh consecutive game at the Coliseum.

Jed Lowrie doubled in Oakland’s run. The A’s were coming off a four-game sweep of the AL East-leading New York Yankees but fell 15½ games behind the first-place Astros in the AL West.

Brad Peacock (4-1) struck out eight in 52/3 innings. He retired 16 of his first 18 batters and didn’t allow a runner past first until Matt Joyce’s one-out double in the sixth.

Three relievers combined to get 10 outs for Houston. Ken Giles pitched the ninth for his 17th save.

Marisnick hit his ninth homer on a 2-2 pitch from rookie starter Daniel Gossett (0-2), a two-run drive that bounced off the façade underneath the lower row of luxury suites in center field.

Springer homered off John Axford leading off the eighth. Fisher’s home run came in the ninth.

The A’s scored their lone run in the sixth. After Joyce doubled and Chad Pinder walked, Lowrie hit a ball into right-center. Joyce scored easily but Pinder was thrown out at home on a relay by star shortstop Carlos Correa.

The double extended Joyce’s hitting streak to seven games. He is 16 for 40 in his past 13 games.
