The final homestand of Ned Yost’s final season as manager of the Kansas City Royals will begin Tuesday with a game against Atlanta, the organization that gave the former Jackson Mets star his first big league coaching job. Yost, 65, who won a World Series with the Royals in 2015, formally announced his pending retirement today. A catcher in his playing days, Yost spent 1976 and part of the ’77 season with the JaxMets, New York’s Double-A club. He had a short big league career before landing a job as Atlanta’s bullpen coach in 1991. He coached for the Braves until 2003, when he was hired as Milwaukee’s manager. He took the reins in Kansas City in 2010 and is the Royals’ all-time winningest manager. The current club is 57-100, headed for its third straight losing season. … Yost is one of five Mississippi-connected managers in the majors; the others are Ole Miss alum Mickey Callaway, former Mississippi Braves manager Brian Snitker, former JaxMets infielder Ron Gardenhire and ex-JaxMets manager Clint Hurdle.
