Royals RHP Zimmer out for season

Kyle Zimmer's winding, injury-pocked road to the big leagues took another detour.

A right-handed pitcher ranked the second-best prospect in the Kansas City Royals' minor-league system, Zimmer is out for the remainder of the 2016 season because he needs surgery to correct thoracic outlet syndrome.

Zimmer, 24, was the fifth overall pick in 2012 but has logged only 222 1/3 innings in the minors because of a series of injuries.

New York Mets right-hander Matt Harvey and Minnesota Twins right-hander Phil Hughes underwent the same surgery. The nerve condition requires surgical removal of a rib to alleviate pressure on nerves.

This isn't the first shoulder injury for Zimmer, who also had issues with his biceps and elbow.
