The Angels called up outfielder Mike Trout from Double-A Arkansas on Friday, which will push Vernon Wells and Bobby Abreu into lesser roles. Los Angeles manager Mike Scioscia said Trout, who hit .163 but showed much promise during a three-week stint with the Angels in July, will start at least three or four times a week. Trout started in right field against the Orioles on Friday night, with regular right fielder Torii Hunter moving to designated hitter. Wells was in left, but Abreu was on the bench. "There will be times Bobby and Vernon are not in the lineup, but [Trout's playing time] is not going to be totally at their expense," Scioscia said. "Peter Bourjos will need a break [in center]. There will be ways to use Mike that won't just affect Vernon and Bobby."
