ST. PETERSBURG, Fla. — Luke Scott had a go-ahead RBI single in the sixth inning after he tied it with a two-run homer in the fifth, leading the Tampa Bay Rays to a 4-3 victory over the Houston Astros on Saturday.

Roberto Hernandez survived a shaky first inning to post the Rays' 14th straight quality start, going six innings and giving up three runs and six hits. He won for the first time in six starts since June 11. Hernandez (5-10) struck out six.

Wil Myers had two hits and scored twice for the Rays, who have won 13 of 15. Fernando Rodney pitched the ninth for his 22nd save.

Brett Wallace homered for the Astros, losers of 11 of 14.

The Astros jumped out to a 3-0 lead behind Wallace's two-run shot, his fourth homer, and Jose Martinez's RBI groundout. Houston had four hits in the first but only two the rest of the way and never got a runner to second base in the final eight innings.

The Rays tied it in the fifth. Scott connected off Houston starter Dallas Keuchel. Yunel Escobar then had a two-out double, stole third and scored on Desmond Jennings' RBI bunt single.

Scott's two-out single in the sixth came off Lucas Harrell (5-10), who relieved with one out.

Scott, who extended his hitting streak to nine games, is hitting .373 with five home runs in his last 23 games.

Keuchel gave up six hits and three runs in 5 1-3 innings.
