The 23-year-old prospect seized the Angels’ starting job behind the plate out of spring training while Max Stassi is away from the team with a hip injury and a family emergency. O’Hoppe is batting .283 with four homers and 13 RBIs in 16 games.
The Angels acquired O’Hoppe from Philadelphia near the trade deadline last season for outfielder Brandon Marsh.
Veterans Chad Wallach and Matt Thaiss are now likely to split duties at catcher for the Angels.
