The Cubs dropped the series opener last night, and they also lost the only rotation reinforcement they acquired at the deadline as Michael Soroka went to the IL with right shoulder discomfort. Precautionary imaging on the shoulder prior to his last start apparently revealed nothing, but Soroka said after the game that “it grabbed me a little bit” and didn’t subside after he reached back for a little extra on his fastball.
Not a great sign under any circumstances, but it’s even worse when you consider how his fastball velocity had fallen off over the last few weeks.
