Javy Báez capped a five-run third inning with his ninth career grand slam, and the Detroit Tigers avoided a series sweep by beating the Houston Astros 7-4 on Wednesday.

Baez’s two-out homer off AJ Blubaugh (0-1), a 24-year-old right-hander making his major league debut, put the Tigers ahead 7-1. All five runs were unearned due to shortstop Jeremy Peña throwing error on Kerry Carpenter's grounder.

Riley Greene tied his career high with four hits.

Brenan Hanifee (2-0) pitched two scoreless innings in relief of Jackson Jobe, who allowed three runs, four hits and four walks in three innings. Detroit has won five of seven and nine of 13.

Blubaugh (0-1) struck out two in a 1-2-3 first and gave up seven runs — two earned — and five hits in four innings with six strikeouts and a walk.

Blubaugh was optioned back to Sugar Land after the game.

Peña hit the first career leadoff home run, the first of his three hits, but Colt Keith hit a two-run homer in the second to put Detroit ahead for good.

Jose Altuve hit a two-run double in the fifth and Victor Caratini homered in the seventh against Tyler Holton.

Holton struck out Yainer Diaz to strand two runners in the seventh and Tommy Kahnle struck out Christian Walker to leave two runners on in the eighth.

Houston went 2 for 10 with runners in scoring position and stranded 12 runners.
