The Angels recalled Weiss from Triple-A Salt Lake on Sunday.
Weiss will give the Angels a fresh arm in the bullpen. The right-hander struggled in the Cactus League while failing to make the major-league roster, and he's registered a 6.75 ERA with a 1.50 WHIP over 12 innings accumulated from 10 appearances in the Pacific Coast League. Ryan Tepera has been designated for assignment in a corresponding move.
