Angels 10, Tigers 0: Mike Trout’s first career grand slam highlighted a nine-run first inning and host Los Angeles cruised to its second straight win in the series.

Peter Bourjos had his second consecutive three-hit game and an RBI and Howie Kendrick drove in two runs for the Angels. Garrett Richards (1-0) took advantage of the early run support to sail through seven innings, allowing two hits and matching his career high with eight strikeouts.

Tigers starter Rick Porcello (0-2) didn’t make it out of the first inning, becoming the first modern-day starting pitcher to allow at least nine earned runs and nine hits in less than an inning. His ERA ballooned from 5.11 to 11.08.

Bourjos led off the first with the first of his three infield singles. The Angels followed with RBI singles from Albert Pujols and Mark Trumbo, a two-run single by Kendrick and another RBI single by Brendan Harris before Trout finished Porcello’s day with his blast to center.

The Tigers put their leadoff batter on base in the second, seventh, eighth and ninth innings. Detroit, which came into the game leading the American League in hitting (.285), is batting .179 over its last four games with three runs scored.
