The following is a listing of all 30 current Major League Baseball (MLB) teams ranked by win-loss record percentage, accurate as of the end of the 2019 season. The records do not include wins and losses recorded by a team's playing time in the National Association of Professional Base Ball Players (NAPP). Counting MLB statistics, the New York Yankees have the highest win–loss record percentage, with .570. The San Diego Padres have the lowest win–loss record percentage, with .461. The San Francisco Giants and Tampa Bay Rays have recorded the most and least overall wins, with 11,165 and 1,686, respectively. The Chicago Cubs lead the association with the most played games, with 21,395. Conversely, the Rays have played the fewest overall games, with 3,412. The Giants have also recorded the most ties in MLB history, with 163; tie games do not count toward the MLB's standings, and have become particularly rare since the advent of a 2007 rule change assuring that tie games can only occur if such a game is the last scheduled between the two teams that season and has no bearing on the postseason.
