Warner enters his 29th season in the Cardinals organization and his first on the Opening Day Major League coaching staff as the third base coach. The 2019 season marks his third straight year in some capacity on the Major League staff with the previous two seasons being transferred onto the Major League coaching staff midway through the season following coaching transactions. Warner has 11 years of managerial experience in the Cardinals organization, most recently as the manager of triple-A Memphis (2012-14) with double-A Springfield (2007-11) and high-A Palm Beach (2005-06) also under his tutelage. In 2003, his managerial career began with the rookie league Johnson City Cardinals of the short-season Appalachian League. In 2005, Warner managed the Palm Beach Cardinals to the Florida State League playoffs, where the squad knocked off the Vero Beach Dodgers in three games (2-1) before winning the league championship in five games (3-2) over the heavily favored Lakeland Tigers. The resilient Palm Beach squad took the title game with home runs in the 9th and 10th innings tying and taking the lead on the road. Warner was named the 2005 George Kissell Award winner by his peers following his efforts. Warner guided his teams to the postseason in five of his first eight years and 6-of-11 overall. His minor league managerial record stands at 734-730 (.501). His coaching career began in 2000 serving as the batting practice pitcher for the St. Louis Cardinals before moving on to take a coaching role for double-A New Haven in 2001. In 2002-03, Warner was the hitting coach for short-season New Jersey (A) and then held the same post with single-A Peoria in 2004. Following his days as a minor league manager, Warner took roles as the team's Minor League Infield Coordinator (2015-16) and then Assistant Field Coordinator (2017-18). Originally a 17th round draft pick (441st overall) by the St. Louis Cardinals in 1991 out of the, now defunct, University of Wyoming baseball program, Warner played nine years in the Cardinals minor leagues covering 792 career games. He batted .267 with 40 home runs and 242 RBI playing a myriad of positions including all infield spots, outfield and made three relief appearances as a pitcher. He played in 238 games as a shortstop, his most at any position. Warner, 50, resides in St. Charles, Mo., with his wife Laura, sons, Colin Michael (1/9/04) and Benjamin Anthony (1/25/10) and daughter Callie Marie (10/2/11). He wears uniform No. 75 to honor the late Darryl Kile (flipping the 5-and7), as the Cardinals have not issued uniform No. 57 since Kile's untimely death in 2002.
