Canning is in line to serve as a bulk reliever in Thursday's contest against the Blue Jays, Jeff Fletcher of The Orange County Register reports.
Canning has a 9.36 ERA and has surrendered nine home runs in 123 plate appearances in the first inning this season, so the Angels are trying something new with the right-hander. He will follow opener Brock Burke, who will presumably work an inning or two before giving way to Canning.
