Quijada (undisclosed) reported to the Angels' alternate training site Sunday, Fabian Ardaya of The Athletic reports.
Quijada missed all of camp for an undisclosed reason, but he's now rehabbing at the team's alternate training site as he works to get back into game shape. The left-hander isn't likely to join the 30-man roster even when he's ready for game action. If he does reach the majors this year, he's unlikely to have a significant role in the bullpen.
