HOUSTON — Hunter Brown struck out nine in seven scoreless innings and Mauricio Dubón hit a two-run homer as the Houston Astros got a big sixth inning for a 4-0 win over the Detroit Tigers on Friday night.
Brown (3-5) allowed five hits, Bryan Abreu pitched a scoreless eighth and Josh Hader struck out one in the ninth to complete the shutout.
The Astros had just one hit on a leadoff double by Altuve when he doubled to left field to start the sixth inning. He scored on a triple by Alex Bregman, which extended his hitting streak to a career-long 15 games.
A sacrifice fly by Yordan Alvarez sent Bregman home to make it 2-0. Yainer Diaz singled with two outs before Dubón homered off Tarik Skubal (8-2) into the seats in left field to push the lead to 4-0.
''Our guys just kept battling and he left some changeups up in the zone,'' Houston manager Joe Espada said. ''We just stayed on him and that's what you do when you have such a quality pitcher on the mound.''
Skubal gave up six hits and tied a season high with four runs in 6 1/3 innings.
''I didn't execute some pitches there and that's a good team,'' he said.
Colt Keith had two hits for the Tigers, who lost for the third time in four games.
