Right-hander Alex Meyer, who was once one of the Angels’ brightest pitching prospects but hasn’t pitched since undergoing shoulder surgery at the end of the 2017 season, was designated for assignment to clear a spot for Peters on the team’s 40-man roster.
Peters, 26, was selected by the Marlins in the 10th round of the 2014 draft out of the University of Texas. He has a 3.37 ERA in 67 minor-league starts.
Peters battled command issues upon making the Marlins’ opening day roster last season and spent the year shuttling between triple-A and the big league club.
