The Kansas City Royals "have shown interest" in veteran starting pitcher , according to MLB Network's Jon Morosi.
However, Morosi added that the Royals "don't appear to be frontrunners" for Wainwright's signature.
Kansas City has one thing working in its favor since new manager Mike Matheny coached the three-time All-Star for seven seasons with the St. Louis Cardinals.
Wainwright started his career with the Atlanta Braves but was traded to the Cardinals in 2003 as part of the J.D. Drew deal before making his MLB debut. His 326 starts for St. Louis are the fourth-most in franchise history.
