OAKLAND, Calif. -- Two days after homering in the eighth inning to break up Yu Darvish's no-hitter, Houston's Carlos Corporan came up with another timely late hit.

Just like that, the Astros have a winning streak and their first series win in nearly two months.

Corporan hit an RBI double off reliever Sean Doolittle in the 11th inning to drive in Jose Altuve, lifting Houston to a 2-1 win over the Oakland Athletics on Wednesday.

"I was ready for the fastball and he threw it," Corporan said. "As soon as I hit it I thought it's either a homer or a double and we're going to score."

Corporan's hit came after Oakland nearly won the game in the bottom of the 10th when Houston left fielder Robbie Grossman made a leaping grab of Chris Young's deep fly at the fence.

It's the first time the Astros have had back-to-back wins since June 15-16 when they took three of four from the Chicago White Sox. That's also the last time Houston won a series.

"That was a big hit by Corporan," Astros manager Bo Porter said. "He's actually got big hits all year. You look at the year [catcher Jason] Castro's having, a lot of that credit goes to Corporan being a great backup and giving him opportunities to take days off."

Altuve singled with one out off Doolittle (3-4) and was headed for third on Corporan's double to left-center when Young bobbled the ball. Altuve alertly rounded third and scored the tiebreaking run while Corporan was caught in a rundown between second and third.

Corporan had entered the game as a defensive replacement in the bottom of the ninth.

"We've been playing pretty good," Corporan said. "Things are going our way now. It's our turn."

Chris Carter homered and Jonathan Villar added two hits for the Astros. Houston has won the first two games of this series after dropping 11 of the first 12 between the two division rivals.

Lucas Harrell (6-13) pitched one inning for the win while Josh Fields earned his second save.

Yoenis Cespedes singled and scored Oakland's run. The A's have dropped nine of 13 and fell two games behind first-place Texas in the West.

"It just seemed like it was frustrating from the beginning and got more frustrating as the game went on," said A's manager Bob Melvin, who was ejected in the eighth inning after arguing a close play at third base.

"You have to try and put that away and keep your wits about you and not get frustrated."

Houston won despite Oakland getting the tying run on base in the bottom of the 11th.

Eric Sogard hit a leadoff double but Fields struck out Alberto Callaspo, Jed Lowrie and Josh Reddick to end it.

Carter, the former A's first baseman, homered off A's starter Jarrod Parker leading off the seventh. It's Carter's third in his past five games.

Brandon Moss's RBI double in the seventh off Houston reliever Phil Humber tied it.

Both starting pitchers were stellar but left with no decision.

Houston's Jarred Cosart, the first pitcher in franchise history to begin his career with five consecutive starts of five-plus innings while allowing two or fewer runs, kept the A's silent early. He allowed only one runner past first base through six innings and didn't give up a fly ball out until Josh Donaldson's sinking liner to center leading off the fifth.

The Astros also backed him with solid defense. Houston turned a double play to end the third, and center fielder Brandon Barnes made a running catch near the wall to rob Seth Smith of extra bases in the sixth.

Parker pitched a career-best 8 1/3 innings for Oakland and had six strikeouts. The right-hander faced just two over the minimum through the fifth and his only mistake came in the seventh when he gave up Carter's team-leading 22nd home run of the season.

Melvin was ejected in the eighth after arguing a call by third-base umpire Doug Eddings.

Sogard doubled leading off the inning but was thrown out on a close play trying to advance on Nate Freiman's deep fly to center. Melvin scampered out of the dugout to dispute the call before getting tossed.
