Houston, TX (SportsNetwork.com) - Colby Rasmus and Hank Conger each drove in three runs as Houston crushed Seattle 13-0 in the finale of this three-game set.
Luis Valbuena added a two-run homer and Marwin Gonzalez had a solo shot to go with two RBI for the Astros, who took the series to erase the memory of a recent seven-game skid.
Lance McCullers (3-1) failed to surrender a hit, but was pulled after five innings with Houston owning a 10-run advantage. He walked four, struck out four and threw 90 pitches, then four other relievers combined to toss a two- hit shutout.
"That wasn't the best we've seen of Lance," Astros manager A.J. Hinch said. "It's a great sign when he can battle through innings, five scoreless and hitless. If those are his bad days, it's a pretty good day."
Austin Jackson doubled and Kyle Seager singled for the Mariners' lone hits. Roenis Elias (3-4) was tagged for eight runs on seven hits while also walking four in just 3 1/3 frames.
Houston jumped out to a 3-0 lead in the first thanks to a two-run single from Rasmus with the bases loaded and Seager's error on a Jake Marisnick grounder which plated the other run.
The Astros tacked on two more in the third on a Marisnick double and Elias' bases-loaded walk to Gonzalez.
Five more crossed the plate in the hosts' turn in the fourth on a Rasmus RBI single, Conger's two-run double and a two-out, two-run homer from Valbuena.
Another bases-loaded walk, this time to Conger, in the fifth brought in George Springer, and Gonzalez launched his third homer of the season to left in the bottom of the sixth to make it 12-0.
Tony Sipp took over for McCullers in the sixth but gave up a one-out double to Jackson to break up the no-hit bid. Joe Thatcher was responsible for Seager's leadoff hit in the seventh.
Will Harris and Josh Fields combined to give up a single walk over the final two frames.
"You have two options. You can either hang your head and feel sorry for yourself. Or you can get back to work and keep grinding," noted Seager.
