Anderson signed a minor-league contract with the Angels on Thursday.
Anderson elected free agency Tuesday after being designated for assignment by the Angels earlier in the week, but he will now return to the organization on a new deal. The right-hander made nine appearances with the Angels before being let go, compiling a 5.94 ERA and 1.50 WHIP with 12 strikeouts over 16.2 innings. He will now look to get into a rhythm with Triple-A Salt Lake in an attempt to potentially get another look with the big-league club later this season.
