Starting pitcher Michael Soroka is heading to the injured list after exiting his first start as a member of the Chicago Cubs early on Monday.

“He said he let a pitch go in the second inning and just didn't feel good,” manager Craig Counsell said. “Finished the inning, but came into the dugout and said his shoulder was not feeling good, so it's an IL.”

It was Soroka's first start with the Cubs after being dealt to the North Side by the Washington Nationals on Thursday. The 28-year-old had thrown 31 pitches over the two frames, striking out three and allowing one run on a homer by Reds catcher Tyler Stephenson.
