The Blue Jays optioned McAdoo to Triple-A Buffalo on Saturday.
The 24-year-old will end up as the odd man out of a roster spot following Daulton Varsho's (wrist) return from the injured list. McAdoo went just 4-for-25 at the plate across eight games during his stint in the big leagues but could still return to the majors later this season if the Blue Jays run into problems with their infield depth.
