Mike Matheny, American baseball player and manager
Michael Scott Matheny (born September 22, 1970) is an American former professional baseball player and current manager of the Kansas City Royals of Major League Baseball (MLB). He played in MLB for 13 seasons as a catcher for the Milwaukee Brewers, Toronto Blue Jays, St. Louis Cardinals, and San Francisco Giants. Matheny later spent seven seasons as the manager of the Cardinals. One of the most accomplished defensive players of his era, he won four Rawlings Gold Glove Awards. As manager, Matheny's teams won one National League (NL) pennant and three NL Central division titles.

From Reynoldsburg, Ohio, Matheny was selected by the Brewers in the eighth round of the 1991 MLB draft from the University of Michigan (UM). He made his MLB debut as a member of the Milwaukee Brewers on April 7, 1994. Matheny established major league records among catchers for consecutive games played without committing an error (252), and consecutive chances fielded without an error (1,565). He is one of three catchers in major league history with an errorless season of at least 100 games, and in 2005, set a Giants single-season team record for catcher's fielding percentage at .999. Matheny has made two World Series appearances—both with the Cardinals—one as a player (2004), and one as a manager (2013). He retired from playing in 2006 due to persisting symptoms of concussion, and has since become an advocate for its prevention and for improved catcher safety.

After his playing career, Matheny coached Little League Baseball. The Cardinals hired him to manage after the 2011 season although he had no professional coaching or managerial experience. In 2012, the Cardinals were wild card winners, and from 2013–15, claimed three consecutive NL Central titles, including winning a career-best 100 games for Matheny in 2015. He became the first manager in MLB history to lead his team to the playoffs in each of his first four seasons, and the fifth to a League Championship Series appearance in each of his first three. In 2018, he became the fourth Cardinals manager to manage the club in 1,000 games.
