Jacob Misiorowski left his start July 28 against the Cub s in Milwaukee with a knee injury. He was placed on the injured list and activated for a start last Friday against the Reds. They hit him hard: five hits, three walks and four runs in 1.1 innings. He threw 54 pitches to record four outs.

Cubs outfielder Kyle Tucker, whose production at the plate has plummeted since July, was diagnosed in June with a hairline fracture in his hand, sources told ESPN.
