HOUSTON — Collin McHugh threw six innings, Marwin Gonzalez hit a two-run single and the Houston Astros defeated the Oakland Athletics 3-0 on Saturday night.

McHugh (1-2) gave up six hits and struck out three. McHugh, who missed the first 3 1/2 months with right shoulder tendinitis and a right elbow injury, has allowed two runs or fewer in four of his six starts this season.

After Jose Altuve and Josh Reddick walked and Yuli Gurriel singled to lead off the fourth, Gonzalez followed with his two-run single. Kendall Graveman (3-4) induced flyouts from Carlos Beltran, Juan Centeno and Derek Fisher to prevent further damage.

Alex Bregman added a solo home run over the train tracks above the left field wall to lead off the eighth.

Houston improved to 12-2 against the A’s this year. Oakland didn’t get a runner past second base as Houston turned six double plays.

Francisco Liriano pitched the seventh, Joe Musgrove the eighth and Tyler Clippard the ninth for his fourth save and first with the Astros.

Graveman allowed two runs and six hits with three strikeouts in six innings. Graveman had his second straight good outing after allowing two runs in seven innings against Baltimore on Monday.
