ANAHEIM, Calif. -- Mike Trout described his first major league grand slam as "just another home run."
Teammate Garrett Richards was pretty grateful just the same for the nine-run first inning to support him against Detroit's Rick Porcello.
Trout's second homer of the season capped the Angels' most productive first inning in almost 18 years, and Richards pitched two-hit ball over seven innings in a 10-0 romp over the defending AL champion Tigers on Saturday.
"It's always good to help your starter out like that. Then they can pound the strike zone and not have to worry too much," Trout said. "We're looking better, staying positive, grinding it out..."
Richards (1-0) struck out eight and walked none. Prince Fielder's leadoff single in the second and Miguel Cabrera's leadoff double in the seventh were the only hits off the right-hander in his second start for the injured Jered Weaver, who is sidelined with a broken bone in his non-pitching arm.
"I don't pay attention to the score. I try to pitch the same, whether it's 9-0 or 0-0," said Richards, who left the dugout during the long inning and played catch with backup catcher Hank Conger in the indoor batting cage to stay loose. "Those kinds of games are a little bit harder to pitch in, just because you don't want to relax. You want to keep going after guys. I stayed aggressive and kept attacking guys."
Richards has pitched into the seventh inning in both starts -- the only one on the staff to make it past the sixth in the team's first 16 games.
"He threw 94-97, and his fastball moves in three different directions, so we don't really know which way it's going to go," catcher Chris Iannetta said. "The hitters don't know either."
The Tigers, who lost Friday's series opener 8-1, were shut out for the third time this season and have scored three runs in their last 42 innings -- two of which came on groundouts.
Porcello (0-2) faced 11 batters, threw 47 pitches and got only two outs -- on a double-play grounder by Iannetta. The right-hander, who gave up an AL-worst 226 hits last season en route to a 10-12 record, has allowed 16 earned runs in 11 innings over his first three starts for a 13.09 ERA.
