Yainer Diaz produced a go-ahead, two-run single in the sixth inning, and the Houston Astros tacked on three runs an inning later to rally past the visiting Detroit Tigers 6-4 on Tuesday.

The Astros won their fourth consecutive home series by orchestrating the comeback, first off Tigers starter Reese Olson (3-2) before extending the rally against Detroit reliever Will Vest.

Houston fashioned both three-run rallies with two outs. Olson dominated the Astros over his first five innings, allowing only four baserunners while preventing any of them from reaching scoring position. But with two outs and Jose Altuve on first in the sixth, the wheels suddenly came off.

Diaz dumped a 2-0 slider from Vest into shallow center field, driving home Paredes and Walker and pushing the Astros to a 3-2 lead. Vest surrendered an additional baserunner in the sixth but limited the damage, only for the Astros to strike again with two outs in the bottom of the seventh.

Olson allowed three runs on four hits and three walks with seven strikeouts over 5 2/3 innings.

Dubon opened the seventh with a single, but Vest moved to the brink of a clean frame when he induced Altuve to ground into a double play, erasing Jeremy Pena, who pushed Dubon to second with a walk. Dubon scored when Yordan Alvarez stroked an RBI single to right for a 4-2 lead, and Paredes chased Vest with a run-scoring triple that drove home Alvarez for a 5-2 lead.

Vest entered his 13th appearance with a 0.75 ERA. He allowed three runs on five hits in one inning.

Diaz delivered an RBI single off Tigers reliever Chase Lee and finished 2-for-4 with three RBIs.

Kerry Carpenter smacked a leadoff home run in the first to spot Detroit a 1-0 lead. Gleyber Torres chased Astros starter Ryan Gusto with an RBI single with two outs in the fifth. Carpenter doubled and scored when Torres homered off Astros closer Josh Hader with two outs in the ninth.
