The Chicago Cubs have made a few alterations to their pitching staff due to injuries. On Wednesday, Javier Assad was put on the 60-day injury list due to an oblique injury.
The most significant injury occurred to the starting rotation when Justin Steele suffered an elbow injury that required Tommy John surgery, the second such surgery for the lefty since 2017.
On Wednesday, the Cubs called up Chris Flexen to take the place Colin Rea occupied earlier in the season.
