Zimmermann allowed one run on two hits and a pair of walks while striking out two across four innings during Tuesday's win over the Red Sox. He did not factor into the decision.

Zimmermann's only damage of the night came from a solo home run off the bat of Kyle Schwarber in the second inning. The southpaw left the game poised for the loss but was rescued by his offense, leaving him with a no-decision. It was Zimmermann's first major-league outing since mid-June due to biceps tendinitis and a severe ankle sprain. The 26-year-old took over the rotation spot that belonged to Keegan Akin, who is out for the season with a left adductor strain, and tentatively lines up for another start Sunday at Toronto.
