BOSTON — Reid Detmers allowed three hits over 6 1/3 innings with seven strikeouts and Taylor Ward matched a season high with three RBI to lead the Los Angeles Angels over the Boston Red Sox 7-0 on Friday night.

The Angels sent seven batters to the plate in the first inning, scoring three runs (one earned) against Boston right-hander Tanner Houck (2-1), who had not allowed a run in his two previous starts this season, spanning 12 innings. Houck matched a career high with seven runs allowed (four earned) on a career-high 12 hits in 5 2/3 innings.

The left-handed Detmers (3-0) had a similar outing to his last – an April 6 win against Boston – when he allowed one run on three hits with a walk and 12 strikeouts in six innings. He had two walks on Friday.

Ward’s two-run homer with two outs in the sixth, scoring Mike Trout who singled, ended Houck’s night with left-hander Brennan Bernardino entering.

Boston made three errors, matching a season high on April 5 against the Angels. The Red Sox are 0-4 at Fenway Park.
