The Cubs had extensive conversations about right-hander Michael Soroka’s drop in velocity before acquiring him at the trade deadline, president of baseball operations Jed Hoyer said Tuesday. They were well aware of his injury history.

The Chicago Cubs are already down their trade deadline rotation upgrade. Right-hander Michael Soroka, who came over from the Washington Nationals in a three-player trade last week, exited Monday's game ( CIN 3, CHC 2) with shoulder discomfort and is headed to the injured list. Soroka was two innings into his first start with the Cubs.
