Stephen Piscotty added an RBI double as the A's backed Mike Fiers (1-1), who lost in Japan last week in his first opening-day start.
Fiers allowed one hit, struck out two and walked three in six innings. Three relievers completed the three-hit shutout that breezed by in 2 hours, 18 minutes.
Trout drew the trainer and Ausmus out in the eighth after he made a hard slide into second and jarred his right leg.
