Cotts signed a minor league contract with the Angels on Sunday, Jeff Fletcher of the Orange County Register reports.
Cotts is scheduled to report to Triple-A Salt Lake, where he'll look to parlay strong performance into a spot in the big league bullpen. The southpaw tallied a 3.41 ERA over 63.1 innings with the Brewers and Twins last season and could be a weapon for the Angels against opposing lefty bats.
