Harrison (8-2) was tagged with the loss Wednesday against the Cardinals, allowing three runs on four hits and no walks in four innings. He struck out two.
This is the third consecutive start for Harrison in which he has failed to make it past five frames. The left-hander has covered just 11.2 innings during that span, giving up eight runs with a 14:2 K:BB, which is just a minor hiccup in his efficient first season with Milwaukee. The 24-year-old will carry a 3.01 ERA and 1.08 WHIP across 83.2 innings into the All-Star Break.
