Cubs placed RHP Keegan Thompson on the 15-day injured list, retroactive to June 27, with a right rib fracture.
It’s unclear exactly when the injury occurred, but the last time that the 29-year-old hurler took the hill he worked a perfect inning against the Giants on Wednesday. No word yet on how long the Cubs expect him to be sidelined for. Ethan Roberts was recalled from Triple-A Iowa in a corresponding move on Friday to take his spot in the Cubs’ bullpen.
