HOUSTON -- George Springer clubbed his career-best 30th home run and was one of six starters to record multi-hit games in the Houston Astros' 12-8 interleague victory over the New York Mets in the opening game of a doubleheader on Saturday at Minute Maid Park.

Springer, who finished 2-for-4 with two runs scored, drilled an 0-2 fastball from Mets right-hander Matt Harvey (4-4) out to left field in the second inning to extend the Houston lead to 6-0.

The Astros (81-53) plated four runs in the first inning off Harvey, who was making his first start since June 14 after being sidelined with a stress injury to the scapula bone in his shoulder.

Harvey allowed seven earned runs on eight hits with three strikeouts over two innings, the shortest outing of his career. Harvey was on a pitch restriction and tossed 70 pitches.

Jose Altuve (3-for-4, three runs) and Josh Reddick (3-for-5, two RBIs) added three-hit games for the Astros, who played their first game at Minute Maid Park since Hurricane Harvey ravaged the Gulf Coast last weekend. J.D. Davis added his third homer in the fifth and finished 2-for-5.

Right-hander Charlie Morton (11-6) allowed two runs on six hits and one walk with nine strikeouts over five innings for the Astros.

Morton surrendered a two-run home run to Mets first baseman Dominic Smith in the fourth inning and, trailing 10-2 entering the seventh, New York pulled to within three runs when Wilmer Flores capped a five-run frame with a grand slam off Astros right-hander Will Harris. For Flores, it was his 18th home run on the season.

The Astros have won consecutive games for the first time since Aug. 18-19 against Oakland.
