Maile was promoted to the Blue Jays' big-league roster Friday, John Lott of the Athletic reports.
The 26-year-old will take the place of Jarrod Saltalamacchia, who was designated for assignment Friday. So far with Triple-A Buffalo this season, Maile has slashed .195/.214/.195 in 42 plate appearances. He'll likely provide mostly defensive value as a backup catcher for the Blue Jays this season.
