Kelly will be looking to rebound from the worst start of his rookie season. Against San Francisco on Wednesday, he gave up nine hits and seven runs (four earned) in five innings. The Cardinals lost 15-0.
With Jaime Garcia slated to return from his left shoulder sprain as soon as Sunday, Kelly needs a strong performance if he hopes to stay in the rotation.
Arizona will send Ian Kennedy to the mound. First pitch is scheduled for 8:15 p.m. ET at Busch Stadium. It can be seen on Fox Sports Midwest.
