Houston's Dallas Keuchel struck out seven over six innings and combined with three relievers on a three-hitter in the Astros' 4-0 win over the Los Angeles Angels at Houston's Minute Maid Park on Saturday.

Right fielder George Springer provided all of the offense Keuchel needed as the left-hander earned his second win of the season. Springer took Angels left-hander C.J. Wilson deep in the sixth inning for his first home run of the young season.

The Angels' starter went 6 2/3 innings, striking out eight. But Wilson walked four and was charged with two earned runs as his record fell to 1-2.

Springer's leadoff home run in the sixth woke up the Astros' slumbering offense. The homer was the first for Springer, who had been scuffling early in the season. His batting average at the end of the game stood at .150.

Houston put the game away the following inning on the strength of a two-out rally capped by left fielder Robbie Grossman's three-run homer -- his first homer of the season and his first RBIs of the year.

That was enough for the Astros' bullpen.

Right-hander Chad Qualls set the side down in order in the seventh, all on strikeouts. Qualls threw 12 pitches in the inning, nine for strikes.

Angels second baseman Johnny Giavotella nicked right-hander Pat Neshek for a leadoff double in the eighth inning, but he was not able to advance and was left stranded.

In a non-save situation, right-hander Luke Gregerson pitched a perfect ninth, striking out two.

NOTES: Houston LHP Dallas Keuchel lowered his ERA to 0.90. ... Astros pitchers combined to strike out 13 Angels. ... Angels RF Collin Cowgill was ejected in the seventh inning for arguing balls and strikes.
