HOUSTON (AP) — Despite the Red Sox having the tying run on third base in the seventh inning, Astros rookie left-hander Brett Oberholtzer wanted to stay in Monday’s game.

Oberholtzer said he told Houston manager Bo Porter that they were going to try and get through the inning.

Oberholtzer delivered.

He struck out Brandon Snyder to end the inning, leaving Jonny Gomes, who had doubled to lead off the inning, stranded at third.

Oberholtzer threw seven shutout innings, and L.J. Hoes scored twice to lead the Astros to a 2-0 win over the Red Sox.

Oberholtzer (2-0) allowed four hits while walking two and striking out two.

In his first two career starts, Oberholtzer has thrown 14 scoreless innings, allowing seven hits.

Hoes and Jonathan Villar each had two hits for the Astros, who snapped a fourgame losing streak.

Houston took a 1-0 lead in the fifth. Hoes led off with a single and stole second and scored on a single by Robbie Grossman.

The Astros added a run in the seventh to make it 2-0. Hoes led off the inning with a double and scored on a suicide squeeze bunt by Brandon Barnes off Junichi Tazawa.

The Red Sox, who lost for the second time in their past seven games, put runners on the corners with two outs in the eighth after a David Ortiz bloop single off Wesley Wright advanced Jacoby Ellsbury to third, but Josh Fields struck out Mike Napoli to end the inning.

Fields struck out the side in the ninth for his first career save.

Oberholtzer did not allow a hit until Dustin Pedroia’s single in the fourth. He was caught stealing to end the inning.

Stephen Drew laced a twoout double to right in the fifth but was left stranded.

Boston threatened in the sixth with a two-out single by Pedroia and a walk to Ortiz, but Oberholtzer got a groundout by Napoli to second to end the inning.

Boston starter John Lackey appeared to have rolled his left ankle to end the second inning, coming off the mound for a soft chopper hit by Matt Dominguez. Lackey threw to first for the third out and hobbled off the field with a trainer and coach, but came back out for the third inning.

“I am sure you guys saw it; I rolled my ankle pretty good,” Lackey said. “I’ve done it several times playing other sports, but it definitely didn’t feel great. I wasn’t going anywhere. I just taped it. I pitched fine.

“I don’t think it affected the way I threw the ball or anything. They were definitely keeping an eye on me to make sure it did not affect my delivery. Nothing happened with my arm.”

Lackey (7-9), who said his ankle will not affect his next start despite limping noticeably after the game, allowed two runs and eight hits with two walks and 10 strikeouts in six innings.

Lackey has lost three straight decisions.
