Basallo (abdomen) is starting behind home plate and batting fifth against the Blue Jays on Sunday, Matt Weyrich of The Baltimore Sun reports.
Basallo was out of Saturday's lineup due to abdominal discomfort but entered the game in the ninth inning as a pinch hitter. He's been cleared to serve as the Orioles' catcher for Sunday's series finale while Adley Rutschman operates as the designated hitter.
