Hunter Brown allowed one hit in six innings to become the first eight-game winner in the majors, and the Houston Astros edged the Tampa Bay Rays 1-0 on Sunday to split a four-game series.

Josh Hader earned his 15th save for the Astros, who scored an unearned run in the first. Jeremy Peña reached on a fielding error by third baseman Junior Caminero and scored on Christian Walker's two-out single off Taj Bradley (4-5).

Houston reliever Bryan King retired two batters and permitted the only other Tampa Bay hit. Bryan Abreu got four outs to set up Hader.

Brown (8-3) didn't give up a hit until Josh Lowe singled to left field leading off the sixth. The right-hander then struck Brandon Lowe before ending his outing with a double play.

The Rays (30-29) outscored the Astros 29-6 in their two wins. Houston (32-27) outscored Tampa Bay 3-1 in its two wins.

Tampa Bay's Taylor Walls was ejected for arguing with plate umpire Nic Lentz with one out in the ninth. Christopher Morel finished the at-bat and struck out. Hader fanned Caminero to end it and hasn't blown a save this season.

Jacob Melton made his big league debut for the Astros, beating out a grounder to second for his first hit after looking at a called third strike his first time up. He started in center field and finished 1 for 3.

Key moment

Already trailing, Bradley had runners at the corners with nobody out in the third. But he struck out Isaac Paredes swinging, got Jose Altuve to pop out and struck out Walker looking to escape unscathed.

Key stat

Brown has a 1.83 ERA in 13 starts — fifth-lowest in the majors.
