Burr will serve as the Blue Jays' opening pitcher for Sunday's game against the Rays, Arden Zwelling of Sportsnet.ca reports.
He'll draw his third opener assignment of the season and his second of September. In his previous two starts, Burr covered one and two innings, so expect him to fall somewhere in that range again Sunday before he turns the game over to the bullpen. Ryan Yarbrough is expected to work in bulk relief behind Burr.
