The Chicago Cubs say they knew the risk when they traded for pitcher Mike Soroka, who saw his velocity drop over his final few starts for the Washington Nationals before the deal. On Monday, Soroka left his first start for the Cubs because of shoulder discomfort,

What makes it even more concerning is that the Cubs knew Soroka had experienced a slight dip in his velocity in his starts leading up to the trade deadline. Soroka underwent an MRI just to rule out anything problematic, with all of the results coming back clean.
