The Angels signed Anderson to a minor-league contract Friday and assigned him to Triple-A Salt Lake.
Anderson was DFA'd by the Angels on Aug. 30 and elected to enter free agency Wednesday, but the veteran right-hander will remain with the Halos in the team's minor-league system. Anderson has appeared in 17 games (six starts) for Salt Lake this season, posting a 4.95 ERA, 1.53 WHIP and 47:21 K:BB over 43.2 innings.
