Major League Baseball (MLB) is the highest level of play in North American professional baseball and is the organization that operates the National League and the American League. In 2000, the two leagues were officially disbanded as separate legal entities, and all of their rights and functions were consolidated in the commissioner's office. Since that time, MLB has operated as a single league. Composed of 30 teams, MLB is one of the four major professional sports leagues in the United States and Canada.
Each team in the league has a manager who is responsible for team strategy and leadership on and off the field. Assisted by various coaches, the manager sets the line-up and starting pitcher before each game and makes substitutions throughout the game. In early baseball history, it was not uncommon for players to fill multiple roles as player-managers; specifically, they managed the team while still being signed to play for the club. The last player-manager in Major League Baseball was Pete Rose, who began managing the Cincinnati Reds in 1984.
As of the end of the 2025 MLB regular season, the longest-tenured active manager with the same team in Major League Baseball is Kevin Cash, who has led the Tampa Bay Rays of the American League since 2015. The longest-tenured active manager with the same team in the National League is Dave Roberts, who has led the Los Angeles Dodgers since 2016.
Connie Mack holds the Major League Baseball record for most games won as a manager, with 3,731, and most managed with 7,755. The all-time leaders in championships won in the World Series era (1903–present) are Joe McCarthy and Casey Stengel, who each won seven championships with the New York Yankees.

Atlanta Braves
The Atlanta Braves National League franchise originated in Boston, Massachusetts in 1871. The team has employed 45 managers, who have led the team in three different cities: Boston (1871–1952), Milwaukee, Wisconsin (1953–1965), and Atlanta (1966–present). The first manager was Harry Wright. The longest-tenured manager is Bobby Cox, who retired at the end of the 2010 season. Cox served as skipper of the Braves for 21 consecutive seasons (1990–2010), and holds the major league record for managerial ejections, with 162. 161 of those games were in the regular season, and 1 game was in spring training. Cox' win–loss record was 2,058–1,638 with the Braves (he previously managed the Toronto Blue Jays). He won four Manager of the Year Awards (1985, 1991, 2004–2005) and led the Braves to 14 consecutive division titles (3 in the National League West and 11 in the East; 1991–2005 excluding the 1994 strike-shortened season), winning one World Series in 1995. Fredi González succeeded Cox as manager. Gonzalez was fired on May 17, 2016. On May 17, 2016, the Atlanta Braves named Brian Snitker as their interim manager and the 47th manager in club history. He was named permanent manager on October 11, 2016. Snitker stepped down on October 1, 2025. On November 3, 2025, the Braves named Walt Weiss their new manager, making him the 48th manager in franchise history.
Miami Marlins
The Marlins franchise entered the National League in 1993 as an expansion team and was known as the Florida Marlins until 2011. The franchise's first manager was Rene Lachemann, who accumulated 285 losses during his four-season tenure. Jim Leyland and Jack McKeon each guided the team to World Series victories, in 1997 and 2003, respectively; however, the team has never won a division title. Marlins managers have never lost a playoff series, and Miami is the only franchise in Major League Baseball to accomplish the feat. McKeon is the franchise leader in wins (281). Joe Girardi won the Manager of the Year Award in his only season managing the Marlins (2006). He is the only manager to win the award while fielding a team with a losing record, and he's the only manager to win with a team that finished in fourth place in its division. Jack McKeon was named the team's interim manager in 2011, having been named to the position following the mid-season resignation of Edwin Rodríguez. At the conclusion of the 2011 season, the Marlins hired Ozzie Guillén to be their manager for the 2012 season; however, he was fired following his first season. The Marlins then named Mike Redmond as their manager. Redmond was subsequently fired on May 17, 2015, and replaced by Dan Jennings on an interim basis. After the 2015 season, Don Mattingly signed a four-year contract to become the club's 15th manager. On September 25, 2022, Mattingly stated that he and the Marlins mutually agreed that he would finish the season as manager, and not return to the role in 2023. On October 25, 2022, Skip Schumaker was hired as team's manager. Schumaker resigned after the 2024 season. On November 11, 2024, the Marlins hired Clayton McCullough as manager.
New York Mets
The successor to two previous National League franchises in New York City (the Giants and the Dodgers), the New York Mets have existed since 1962 and have played in Queens since 1964, when they vacated the Polo Grounds in Manhattan and moved to Shea Stadium. Casey Stengel was the first of twenty managers. Gil Hodges led the team to their first championship in the 1969 World Series. Davey Johnson is the franchise leader in regular-season wins, with 595 during his seven-season tenure, and he led the Mets to their most recent title in the memorable 1986 World Series. Bobby Valentine managed the team during their next deep playoff run to the 2000 World Series. Terry Collins holds the record for most games managed at 1134, and his Mets record was 551–583. Combined with his managerial tenures with the Houston Astros and Anaheim Angels, his record was 995–1017. The Mets made the playoffs in Collins' fifth season as manager, and played in the 2015 World Series. Terry Collins retired after the 2017 season and was replaced by former Indians Pitching Coach Mickey Callaway who became the club's 21st manager. After two lackluster seasons Callaway was fired on October 3, 2019. On November 1, 2019, the Mets hired their former All-Star center fielder Carlos Beltrán to be their 22nd manager. After Beltran was implicated in the Houston Astros sign stealing scandal, he and the Mets agreed to a mutual parting of ways. On January 22, 2020, the Mets hired quality control coach Luis Rojas as the team's next manager. After 2021 season, the Mets announced that they would not pick up the 2022 option for Rojas. On December 20, 2021, Buck Showalter was announced as the club's 24th manager. Showalter announced that he won't return to the Mets for 2024 season. Carlos Mendoza was named as manager on November 13, 2023. Mendoza was fired during the 2026 season. Andy Green was hired as interim manager.
Philadelphia Phillies
The National League franchise in Philadelphia was established in 1883 following the dissolution of Worcester. The team adopted the Philadelphia Phillies name in 1884 and has used the moniker since that time. The team's first manager was Bob Ferguson. Charlie Manuel was the manager from 2005 to 2013 until he was fired on August 16, 2013. Manuel was the first Phillies manager since Dallas Green in 1980 to win a World Series (2008) and the first to lead his team to at least three consecutive playoff appearances since Danny Ozark (1976–1978). Manuel's career managerial record is 867–678, having previously managed the Cleveland Indians; his record with the Phillies was 780–636 surpassing Gene Mauch's previous regular season record of 645 wins (1960–68). The Phillies won five consecutive division championships (2007–2011) and back-to-back National League pennants (2008–2009) during Manuel's tenure. Manuel has the most postseason wins (27) in team history, while Ozark has the most playoff losses (9). Larry Bowa is the only Phillies skipper to capture the Manager of the Year Award, which he won in 2001. Four Phillies managers have been inducted into the Philadelphia Baseball Wall of Fame for service to the Phillies: Paul Owens, Bowa, Gavvy Cravath, and Green. Following Charlie Manual's firing in 2013, 3rd base coach Ryne Sandberg was promoted to manager. Sandberg resigned on June 26, 2015, and Pete Mackanin was the hired as a replacement. On September 29, 2017, the club announced that Mackanin would not return as manager. The following day, the Phillies hired Gabe Kapler to be their 54th manager. After two unsuccessful seasons with the club, Kapler was fired. On October 24, 2019, the Philadelphia Phillies hired Joe Girardi as their 55th manager, replacing Kapler. Girardi was fired after a disappointing start to the 2022 season and was replaced by bench coach Rob Thomson. Thomson was fired on April 28, 2026. Don Mattingly was named as interim manager for the remainder of the 2026 season.
Washington Nationals
The Washington Nationals franchise was established in Montreal, Quebec in 1969 as an expansion team. Originally known as the Montreal Expos, the team's first manager was Gene Mauch, who led the team for seven seasons. Felipe Alou is the manager with the most wins (691) and losses (717) in franchise history. He won the 1994 Manager of the Year Award with the club. Jim Fanning was the only Expos club manager to appear in the Major League Baseball postseason; his .529 regular season winning percentage was the highest in franchise history. The only other Expos manager with a winning percentage above .500 is Buck Rodgers (.510), who won the 1987 Manager of the Year Award. After the team relocated to Washington, D.C. in 2004, Dusty Baker was hired as the manager on November 3, 2015, and fired on October 20, 2017. On October 29, 2017, the Nationals named Dave Martinez as their 31st manager. Martinez led the team through their longest ever playoff win through their first World Series title in 2019. Martinez was fired on July 6, 2025. Miguel Cairo was named interim manager the next day. On October 31, 2025, Blake Butera was announced as the new manager of the Nationals. At age 33, he became the youngest MLB manager since the Minnesota Twins hired Frank Quilici in 1972.

Chicago Cubs
The Chicago Cubs franchise began as the Chicago White Stockings in 1876, with Albert Spalding as the franchise's inaugural manager. The team's second manager, Cap Anson, set team records in games managed (2,194), seasons managed (18), and wins (1,242). Frank Chance, part of the famous Tinker to Evers to Chance double-play combination—all of whom managed the franchise at some point—has the best winning percentage in club history (.664) and led the Cubs franchise to World Series victories in 1907 and 1908. During the early 1960s, owner Philip K. Wrigley utilized a "College of Coaches", using a rotating system of multiple managers rather than a single field leader. Lou Piniella managed the Cubs from 2007 to 2010 and led the team to consecutive postseason appearances in 2007 and 2008, becoming the first manager to lead the team to multiple postseasons since Charlie Grimm's four appearances from 1932 to 1935. Dale Sveum was hired for the 2012 season and fired after the 2013 season. Rick Renteria replaced Sveum as manager. Sveum was fired after the 2014 season. On November 2, 2014, Joe Maddon was named the club's 60th manager. On October 24, 2019, the Cubs hired former catcher David Ross as their 61st manager. On November 6, 2023, the Cubs made a surprising move to fire Ross, and hired former Brewers manager Craig Counsell as the team's 62nd manager.
