Choi won an Opening Day roster spot with the Angels, Joey Kaufman of the Orange County Register reports.
Choi, a Rule 5 selection, wasn't a standout in spring training, but the Angels saw enough in him to keep him on the 25-man roster rather than return him to the Orioles. Though he'll be available off the bench, it's hard to envision Choi seeing many at-bats while both C.J. Cron and Albert Pujols remain healthy.
