Trout hit his 30th homer Sunday, a two-out solo shot in the seventh inning at Texas off Yu Darvish.
The 21-year-old Trout had a leadoff walk to start the game, then quickly got his 48th stolen base.
Only two players in the majors have ever had 30 homers and 50 stolen bases — Eric Davis in 1987 and Barry Bonds in 1990.
The Angels have four games left in the regular season, including the second game of Sunday's day-night doubleheader against the AL West-leading Rangers.
