SAN FRANCISCO -- Sensing a change in fortune was about to occur, one of Scott Feldman's high school friends convinced his boss to give him the keys to his luxury suite at AT&T Park on Wednesday afternoon.

Turns out the guy knew what he was doing.

Pitching in front of more family and friends than usual in his third San Francisco homecoming, Feldman combined with four relievers on a five-hit shutout, earning the Houston Astros a series split with the San Francisco Giants with a 2-0 victory.

"This means something for the people who have supported me," declared Feldman, who grew up in the San Francisco suburb of Burlingame. "I guess I'd never won here before. Yeah, it's nice for me, and it's nice for them."

Center fielder Colby Rasmus and third baseman Jed Lowrie belted solo home runs to provide all the scoring and enable the Astros (62-53) to fly home from a nine-game trip with a second win.

"We're certainly going home on a happy flight," Astros manager A.J. Hinch said after his club improved its best-in-baseball interleague record to 11-3. "This road trip was rough, but that's in the past. You just have to win today's game -- and today we did."

The Giants (60-53) won the opener of the two-game series 3-1 on Tuesday night behind the complete-game effort of left-hander Madison Bumgarner.

Wednesday's loss was just the second in their last 11 home games.

"We didn't generate any offense," observed Giants manager Bruce Bochy, whose team suffered its 10th shutout defeat of the season. "I thought we would today. We got some momentum (in Tuesday's win). But he (Feldman) did a good job on us."

Rasmus broke a scoreless tie with a home run, his 15th of the season, off Giants starter Chris Heston leading off the seventh inning.

The blast was his second go-ahead homer in the Astros' last three games. He also put Houston ahead 4-3 in the top of the ninth inning Sunday at Oakland with a three-run homer, only to see the Athletics rally for a 5-4 win.

"Big hit," Hinch assured. "We needed something to bust out for this offense to exhale."

Coming off a pair of road starts in which he was roughed up for eight runs in 8 2/3 innings, Heston (11-7) limited the Astros to just the one run in 6 1/3 innings. He allowed three hits, walked four and struck out four.

"You've got to try to stay positive and build off positives in these starts," said Heston, who is winless in three starts in August. "I built off the rough one in Chicago and was able to do some good things today. I'll use this as a stepping stone for the next one."

Lowrie connected off Giants reliever George Kontos with two outs in the eighth to complete the scoring. It was his fifth homer of the year and first of his career against San Francisco.

The homers were the 157th and 158th of the season for the Astros, who lead the majors in the department. They have connected two or more times on 46 occasions, winning 39 of those games.

"There was a little frustration," Lowrie said of a trip in which the Astros suffered six defeats by two runs or fewer. "But I think we've done a pretty good of maintaining a level head through this."

The home runs provided more than enough support for Feldman and his mates, who teamed for Houston's 11th shutout of the season.

Feldman (5-5), who entered the game with an 0-4 record against the Giants and 0-2 mark at AT&T Park, left for a pinch hitter in the top of the seventh inning, having allowed four hits and one walk in six shutout innings. He struck out four.

"Every game matters," he said about the Astros putting the previous losses on the trip behind them. "You try not to put any extra pressure on yourself. But at the end of the day, every win is important."

Left-hander Oliver Perez pitched two-thirds of an inning, righty Will Harris stranded Giants shortstop Brandon Crawford at second base by getting the final out of the seventh in a 1-0 game, righty Pat Neshek worked a perfect eighth and closer Luke Gregerson picked up his 23rd save with a 1-2-3 ninth.

Gregerson's outing was his first since allowing two runs in the bottom of the ninth in Sunday's 5-4 defeat at Oakland.

Like the Giants, the Astros recorded just five hits in the game.

Crawford and left fielder Gregor Blanco had doubles for the Giants, who fell to 11-6 in interleague play.

The loss was just the Giants' fourth in their last 20 interleague games at AT&T Park.

NOTES: Astros CF Carlos Gomez was not in the starting lineup after banging his knee into the center-field fence making a spectacular catch Tuesday night. He flied out as a pinch-hitter in the seventh inning. ... Astros manager A.J. Hinch said he expects OF George Springer (broken right wrist) to begin baseball-related activities later this week. Springer hasn't played since July 1. ... Astros RHP Brad Peacock had season-ending surgery to remove bone spurs from his back that were pinching a nerve near his spine. The veteran pitched only one game for the Astros this season. ... Giants LF Nori Aoki played for the first time since getting hit in the head by a pitch Sunday in Chicago. But he had to leave the game in the fifth inning after experiencing light-headedness. ... Three injured Giants starting pitchers -- RHP Mike Leake (strained left hamstring), RHP Tim Hudson (strained right shoulder) and RHP Tim Lincecum (contusion on right forearm) -- threw bullpen sessions before the game. Manager Bruce Bochy indicated Leake is in line to come off the disabled list next Tuesday to start in St. Louis, while Hudson is slated to be sent to Triple-A Sacramento on an injury-rehab assignment later this week.
