HOUSTON (AP) -- The Los Angeles Angels finally showed off their high-powered offense to win their first game of the season.
Mike Trout, Josh Hamilton and Kole Calhoun all homered to help the Los Angeles Angels get their first win of the season with an 11-1 rout of the Houston Astros.
Marc Krauss drew a walk in five plate appearances as the Astros' left fielder.
After being swept in a three-game series against Seattle to begin the season and scoring just eight runs over the three games, the Angels equaled that in the first six innings Friday.
"I think with a game like this, hopefully, we build confidence," Angels manager Mike Scioscia said. "Hopefully, on the offensive side we build confidence."
Trout hit a solo homer in the first inning and Hamilton hit a three-run drive in the sixth off Jerome Williams that made it 8-1. After Erick Aybar's RBI single, Calhoun added a two-run shot off Williams in the seventh.
"As competitors, five out of eight games, we are capable of doing something like that," Hamilton said. "The talent is there. We don't go out and try to do that every day. We go out and have the at bats we are going to have. That's contagious. That's the mentality we have."
Trout also threw out Marc Krauss at the plate in the second inning to keep the Astros off the scoreboard.
Garrett Richards (1-0) allowed one run on three hits with five walks and seven strikeouts in five innings.
"It's not just me, it's all of us," Trout said. "It just happens that I got a home run, but look at Josh tonight. . We just have to keep pushing together, and we pitched well tonight with Garrett getting out of some battles and jams."
Lucas Harrell (0-1) was roughed up for five runs on seven hits with three walks and three strikeouts in three innings.
"With a lineup like that, they have so many good hitters you can't leave the ball over the plate like that," Harrell said. "You go from one hitter to the next, and there is no let-up. That's why they are so good. You have to execute your pitches every time. I just left it over the plate too many times."
Jose Altuve had two hits and a bases-loaded walk in the fifth inning.
The Astros loaded the bases in the fifth and sixth innings but were only able to get the one run as Richards struck out Krauss to end the fifth and Fernando Salas struck out Marwin Gonzalez and induced an Alex Presley ground out to end the sixth.
