Canning will be used as a bulk reliever behind opening pitcher Kyle Hart for Thursday's contest in Atlanta, Jeff Sanders of The San Diego Union-Tribune reports.
The Atlanta lineup features three left-handers in its top four spots (Drake Baldwin, Matt Olson and Michael Harris), so San Diego will have the left-handed Hart cover the first inning or two before the right-handed Canning takes over. Righties have posted a .628 OPS against Canning this season, while lefties have pummeled him for a .939 OPS.
