Manager Joe Maddon said Sandoval reported to camp Thursday, Fabian Ardaya of The Athletic reports.
Sandoval has officially joined the Angels for workouts after missing the start of summer camp for undisclosed reasons. The southpaw, who posted a 5.03 ERA, 1.37 WHIP and 42:10 K:BB over 39.1 innings as a rookie last season, is a candidate to serve as the team's sixth starter during the shortened 2020 season.
