Huff was designated for assignment on Monday, Pedro Moura of the LA Times reports.
After being called up on June 6, Huff started two games for the Angels, pitching a total of 5.1 innings and allowing 10 runs (seven earned) off 13 hits and two walks. He'll almost surely end up in the minors, where he's struggled in 2016. Huff's ERA and WHIP at the Triple-A level are sitting at 4.58 and 1.44, respectively. Batters are hitting Huff with ease, as his opponent batting average is .308.
