# List of all-time Major League Baseball win–loss records

Major League Baseball (MLB) is a professional baseball organization, which consists of a total of 30 teams—15 teams in the National League (NL) and 15 in the American League (AL). The NL and AL were formed in 1876 and 1901, respectively. Beginning in 1903, the two leagues cooperated but remained legally separate entities until 2000 when they merged into a single organization led by the Commissioner of Baseball. This list documents all 30 active MLB teams ranked by win–loss percentage as of the completion of the 2024 Major League Baseball season. These records do not include results from a team's playing time in the National Association of Professional Base Ball Players or while members of any minor league.
The New York Yankees has the highest regular season winning percentage, with .569. The Miami Marlins have the lowest, with .459. The San Francisco Giants have the most overall wins (11,541), while the Arizona Diamondbacks have the fewest (2,087). The Philadelphia Phillies have the most losses, with 11,326, while the Tampa Bay Rays have the fewest, with 2,179. With 22,255 games played, the Chicago Cubs have played more games than any other MLB club. Conversely, Tampa Bay has played the fewest (4,270). San Francisco has recorded the most ties in MLB history, with 163. Tie games do not count toward MLB standings and they have become scarce since the advent of a 2007 rule change assuring that a tie game can occur only if it is the last scheduled matchup between the two teams that season and has no bearing on the postseason.
As of the completion of the 2024 World Series, the Miami Marlins have the highest postseason winning percentage, with .600, while the Minnesota Twins have the lowest, with .379. The New York Yankees have the most postseason wins (252), while the Colorado Rockies have the fewest (10). The Yankees also have the most postseason losses (184), while Colorado has the fewest (14).
