Waldichuk, who was originally slated for a conventional start Sunday against the Padres, will now serve as the primary pitcher behind opener Joe Boyle, who is expected to be called up from Triple-A Las Vegas, MLB.com reports.
Waldichuk served as a bulk reliever in his most recent appearance last Sunday against the Astros and turned in a gem, spinning a six-inning no-hit effort. The left-hander hasn't allowed more than two earned runs in an appearance of any kind since Aug. 1, generating a 1-0 record and 1.91 ERA over the 37.2 innings covering his subsequent seven outings. Given that Waldichuk is fully stretched out for a starter's workload, he could end up getting 5-to-6 innings Sunday, depending on how long Boyle stays in the game.
