The Blue Jays designated MacIver for assignment Monday.
Acquired from the Rangers in late April, MacIver didn't end up seeing any playing time at the big-league level with the Blue Jays during his time on the 40-man roster. The Blue Jays will expose the 29-year-old catcher to waivers after he produced a .270/.344/.459 slash line with seven home runs and four steals in 60 games at Triple-A Buffalo.
