McKenzie was placed on the 10-day injured list with right shoulder fatigue Wednesday, retroactive to Aug. 22, Zack Meisel of The Athletic reports.
McKenzie earned the win in his most recent start when he allowed a run on two hits and a walk while striking out eight in seven innings against the Angels on Saturday. However, he's apparently dealing with a shoulder issue that will force him to miss at least one turn through the rotation. Logan Allen was recalled from Triple-A Columbus in a corresponding move, and he's an option to take McKenzie's place in the rotation.
