The Angels optioned Reyes to Triple-A Salt Lake on Friday, Sam Blum of The Athletic reports.
This move clears a 26-man roster spot for Lucas Giolito, who was acquired from the White Sox on Wednesday and will make his Angels debut in a start Friday night against the Blue Jays. The 30-year-old Reyes has allowed six runs (five earned) in 6.2 major-league innings this year.
