Yarbrough is expected to serve as a bulk reliever behind opening pitcher Ryan Burr in Sunday's game against the Rays, Arden Zwelling of Sportsnet.ca reports.
The lefty hasn't made a start for Toronto since being acquired at the trade deadline July 30, but he should be ticketed for his third outing as a bulk reliever behind Burr. When Burr previously made one- and two-inning starts Aug. 22 against the Angels and Sept. 9 versus the Mets, respectively, Yarbrough followed him and covered five and 3.2 innings out of the bullpen. Yarbrough will be pitching on three days' rest Sunday after logging two scoreless innings out of the bullpen Wednesday against the Rangers.
