Carlos Quentin clubbed a go-ahead RBI double in the top of the 10th inning to lift the Padres to an 8-7 victory over the Astros in the opener of a four-game series Monday at Minute Maid Park.

Brandon Lyon (0-2) entered in the 10th for the Astros and issued a one-out walk to Chase Headley. Headley quickly swiped second before coming around to score on Quentin's go-ahead double to right.

"The last number of games for Carlos (Quentin), he's just been a tick off. So hopefully, two hits tonight, hard line drives up the middle the other way, gets him going again," San Diego manager Bud Black said. "That was a huge hit."

Huston Street fired a scoreless bottom of the 10th to record his 11th save of the year and nail down San Diego's third win in their last four tries.

Jesus Guzman crushed a two-run homer in the eighth, while Dale Thayer (1-2) earned the victory after tossing a perfect ninth.

Brian Bixler and Carlos Lee each hit solo shots in the first and Jason Castro added a solo blast in the eighth to knot the game at 7-7, but the Astros lost for the seventh time in their last 10 games.

Castro's two-out homer in the eighth came after Guzman gave the Padres a 7-6 lead in the top of the frame with a two-run shot into the left-field seats.

Earlier in the game, Bixler and Lee gave the home team a 2-0 lead in the first, but the Padres battled back in the second as Guzman and Logan Forsythe stroked consecutive one-out singles to put runners on the corners before Everth Cabrera's bunt single scored Guzman from third.

Nick Hundley then ripped a double to left to plate Forsythe and Cabrera before coming around to score two batters later on Chris Denorfia's single to right to give the visitors a 4-2 advantage.

Houston responded in the bottom half as Castro clubbed a leadoff double and quickly scored on a single to center from J.D. Martinez to bring the Astros within a run.

San Diego restored its two-run lead in the third as Quentin singled, moved to second on a fielder's choice and crossed home on Fosythe's base hit to right.

Bixler doubled to start the bottom of the fourth, but back-to-back fly outs found him stuck on second. Brian Bogusevic then worked a two-out walk and Chris Johnson plated Bixler with a line drive to center to make it 5-4 game.

A walk to Castro then loaded the bases before Martinez followed suit with a four-pitch walk to plate Bogusevic and tie the game at 5-5.

Houston then jumped in front in the fifth as Bixler coaxed a one-out walk and moved to second on Brad Boxberger's errant pickoff attempt to first. Jed Lowrie then clubbed a double to right, scoring Bixler and giving the Astros a 6-5 advantage.

"We were one big hit away," said Houston manager Brad Mills, whose team left the bases loaded in the second, third and fourth innings and stranded 13 runners on base.
