Kyle Zimmer entered the 2016 season as the Kansas City Royals second-best prospect. The former top-five pick of the organization will now miss the remainder of the season with something called the thoracic outlet syndrome.
Without getting into too much detail here, the syndrome can impact nerves of the upper extremities and can cause weakness in the arm. It's the same issue that forced New York Mets starter Matt Harvey to shut it down for the season earlier this month.
Zimmer, 24, was limited to just three appearances between high Single-A and Double-A ball prior to suffering the injury.
While this has no impact on fantasy baseball this season, those expecting to potentially add Zimmer in dyno drafts during the winter might want to hold off on making that decision. In addition to the injury, the top prospect boasts a four-plus ERA in parts of five Minor League seasons.
