Angels 4, Astros 1: Mike Trout and Josh Hamilton homered to lift host Los Angeles to its second straight victory.

Hamilton had three hits and three RBIs and Trout had two hits and scored three runs for the Angels, who have won two in a row for the first time. Angels starter C.J. Wilson (1-0) pitched six innings, allowing one run and five hits to lower his ERA to 4.00.

Trout, who hit 30 home runs last season on his way to winning American League Rookie of the Year honors, hit his first this season, a towering opposite-field blast into the seats in right-center field off Houston starter Philip Humber (0-3) in the third inning to give Los Angeles a 2-1 lead. Humber threw seven innings, allowing two runs and seven hits.

The Angels took a 1-0 lead in the first inning after Trout doubled with one out and came home on Hamilton’s two-out single to shallow center. The Astros got even in the second on back-to-back doubles by Ronny Cedeno and Matt Dominguez.

Hamilton homered for the second consecutive game in the eighth, an opposite-field two-run shot that barely drifted over the fence in left-center to give the Angels a 4-1 lead.

GAME NOTEBOOK: The Angels used three consecutive left-handed pitchers against the Astros. Sean Burnett relieved Wilson and got three ground-ball outs in the seventh inning. Scott Downs came on in the eighth and got two outs before the Angels called on closer Ernesto Frieri, who struck out pinch-hitter Jason Castro with runners on first and second and went on to earn the four-out save, getting all four outs on strikeouts. … Hamilton started the season 1-for-20 but has since gone 10-for-27. … Humber’s ERA dropped to 2.89 but he remains winless.
