Manager Charlie Montoyo said there is a "good chance" Mayza (elbow) will be activated from the 10-day injured list prior to Wednesday's game against the Nationals, Ben Nicholson-Smith of Sportsnet.ca reports.
Mayza was placed on the injured list Aug. 7 with elbow inflammation, but he was able to return to the mound for a rehab assignment with Triple-A Buffalo on Sunday. It sounds like he's on track to rejoin the Blue Jays' bullpen after just the one rehab outing, though a roster move won't become official until Wednesday.
