Detmers is not listed as Sunday's starter against the Athletics.
The Angels will give Carson Fulmer the ball Sunday, and given that Detmers hasn't followed an opener all season, it would seem that he is done for the year. The 24-year-old southpaw logged a 4.48 ERA, 1.35 WHIP, 168 strikeouts and four wins over 148.2 innings.
