ANAHEIM, California — Yainer Diaz homered in his fourth consecutive game and drove in three runs, and Framber Valdez pitched a four-hitter in the Houston Astros' 7-1 victory over the Los Angeles Angels on Friday (Saturday in Manila).

Yordan Alvarez hit a tiebreaking three-run double in the five-run seventh inning by the Astros, who opened a weekend series at the Big A with their fifth win in eight games.

Diaz connected for a two-run shot moments after Alvarez put Houston ahead, giving him nine RBIs in the past four games. Diaz homered in every game earlier this week, and his blast to left off the Angels' Hunter Strickland was his seventh of the season.

Before this week's power surge, Diaz had just one homer in his previous 51 games and none in 39 games since April 11. He hit 23 homers last season in his first full big-league campaign.

Valdez (5-3) struck out eight and issued his only walk in the ninth inning of his seventh complete game and his first.

Valdez frequently dominates the Angels, including three career outings with at least 12 strikeouts, along with five victories in eight career starts at Angel Stadium. José Abreu also homered in the eighth for Houston.

Kevin Pillar homered for the Angels, whose three-game winning streak ended just short of matching their longest run of the season. Griffin Canning (2-6) allowed three runs on seven hits while pitching into the seventh inning.

Houston only got two runners past first base in the first six innings, but Trey Cabbage and José Altuve singled to chase Canning in the seventh.

Alvarez then put a long double in the gap off Strickland moments after Alex Bregman drew a walk. Pillar tied it on the first pitch of the second inning, blasting it 411 feet for his seventh homer of the season.
