Thoracic Outlet Syndrome is the new black, apparently. Matt Harvey underwent his surgery for it this week and now Royals prospect Kyle Zimmer will as well. He’s out for the year.
Zimmer was the fifth overall pick in the 2012 draft and was ranked as a top-25 prospect according to both Baseball America and MLB.com heading into the 2014 season. He experienced numerous arm problems that year, however, and had “minor” shoulder surgery in that October. He pitched well, primarily in relief, across two levels in 2015 but has only pitched sparingly this season. He turns 25 in September.
While the timeline for Thoracic Outlet Syndrome surgery could have him back for spring training, recovery from it is unpredictable and it’s certainly going to cut into any offseason program Zimmer was going to pursue. Tough break for a kid who has had a few of them already.
