HOUSTON -- Houston Astros shortstop Carlos Correa took such a measured, veteran approach in his second plate appearance on Thursday that the subsequent result, a key home run, made clear that he was not lacking in confidence in that moment.

Correa smashed a pair of two-run homers in consecutive at-bats and the Astros claimed the rubber match of their three-game series with the Oakland Athletics with a 6-1 victory at Minute Maid Park.

Correa finished 2-for-3 with a walk and four RBIs to help carry the Astros (54-26) to their first home series victory following three consecutive home series losses. Correa belted both homers, his 15th and 16th, off Oakland starter Daniel Gossett.

His first blast the opposite way to right-center field landed in the Houston bullpen and erased a 1-0 deficit in the bottom of the fourth. Gossett (1-3) retired the first 10 batters he faced before Astros left fielder Josh Reddick hit a one-out double to left two batters before Correa delivered his two-out blast for a 2-1 lead.

"He's a new pitcher in the league so we've got to see what he's throwing and his patterns and what he likes to use more," Correa said of Gossett. "His slider is his out pitch so I figure 3-2 I would get one of those."

After the Astros loaded the bases with no outs but failed to score in the fifth inning, Correa chased Gossett with a 435-foot blast to straightaway center in the sixth, driving home Jose Altuve, whose double to right-center scored Reddick.

"He fooled me with a slider on the pitch before so I figured he would try to come in with a fastball," Correa said. "And he left it down the middle so I was able to put a pretty good swing on it and drive it."

Reddick finished 2-for-3 with an RBI and scored twice. Evan Gattis went 2-for-4.

Astros right-hander Brad Peacock (5-1) struggled with his control, issuing a career-high-tying six walks over five innings. But he allowed just two hits and totaled seven strikeouts, surrendering his lone run on a fielder's choice grounder by Athletics third baseman Adam Rosales in the fourth.

"He did a good job of staying calm in these big moments because he went with the bend-but-don't-break style that can get you in trouble, which is uncharacteristic," Astros manager A.J. Hinch said of Peacock. "He's not a big walk guy. He wasn't missing by a ton. He was missing by inches, not feet.

"It was a good game for him to get through five innings. It was a grind for him. But when you look up at the end of the day he had a really good game. It was just a little bit difficult for him to get his rhythm, get his timing and get the results."

The Athletics (35-44) managed only three additional hits off the three-man Houston bullpen of Chris Devenski, Reymin Guduan and James Hoyt, and fell to 2-10 against the Astros this season. Oakland did manage a 4-2 road trip, however.

"Compared to what we've been doing, we'll take it," Athletics manager Bob Melvin said. "Hopefully it's something to build on and have more confidence when we go into Seattle (July 6) knowing that we've played better on the road."

Gossett allowed five runs on seven hits and one walk with one strikeout over five-plus innings. He credited his defense, with right fielder Matt Joyce and Rosales making fabulous plays, for his fast start and bemoaned his inconsistency for when the Astros strung together their extra-base hits in the middle innings.

"Defense was a huge part early, then I didn't make my pitches late," Gossett said. "It's tough to have good defense when they hit it out of the park. Just got to make better pitches, more consistent pitches."

NOTES: Athletics 1B Yonder Alonso was unavailable with lingering soreness after fouling a ball off his right knee in the eighth inning on Wednesday night. Alonso, who is the best chance to represent Oakland in the All-Star Game, remains day-to-day. ... Astros RHP Charlie Morton (right lat strain) threw a bullpen session on Thursday and will pitch again on Sunday, either for Houston in its series finale against the Yankees, or during a third rehab start. ...
