The Angels optioned Wantz to Triple-A Salt Lake on Sunday.
Wantz allowed two runs over two innings out of the bullpen in Saturday's 6-2 loss to the Twins, so the Angels will swap him off the 26-man active roster for a fresh arm heading into Sunday's series finale. The right-hander has now been demoted three times this season, despite delivering a 3.32 ERA, 0.97 WHIP and 20:8 K:BB in 21.2 innings with the big club.
