Nathan Alan Karns came to the Kansas City Royals this past off-season. The team sent OF Jarrod Dyson to the Seattle Mariners to get the right hander. Karns came with an inconsistent past, but definite upside. In 44 2/3 IP for the Royals Karns was 2-2 with a 3.43 ERA. Unfortunately for the team he has been on the disabled list since May.
After searching for the reasoning behind Karns’ “dead arm” symptoms there has finally been a diagnosis. The 29 year old will undergo surgery for thoracic outlet syndrome. The procedure removes a rib that relieves pressure on a nerve in the arm.
