The Angels acquired Baumann from the Giants on Tuesday in exchange for cash, Robert Murray of FanSided.com reports.
San Francisco designated Baumann for assignment Saturday, but he'll regain a 40-man roster spot with a new organization. He's out of minor-league options and thus will need to be added to the Angels' 26-man active roster. The right-hander reliever holds a 4.84 ERA and 1.44 WHIP over 35.1 innings across 36 appearances with the Giants, Mariners and Orioles.
