List of MLB teams with the most wins in a season as of 2023

Only two teams—the 1998 New York Yankees and the 2001 Seattle Mariners—have achieved the best MLB record ever in 162 games. Their winning percentage was above .700 over the entire season since the season's length was increased to 162 games in 1961. The nine MLB teams with at least 109 victories are shown below.

9. 1961 | New York Yankees: 109-53

The 1961 New York Yankees season marked the team's 59th campaign. The team won the American League pennant for the 26th time with a final record of 109-53, eight games better than the Detroit Tigers.

They prevailed over the Cincinnati Reds in five games in the World Series. The home run race between Roger Maris and Mickey Mantle, in which the former broke Babe Ruth's single-season record by hitting 61, was the highlight of this season. The 1961 Yankees are mostly listed as candidates for the unofficial title of the greatest baseball team in history.

9. 1969 | Baltimore Orioles: 109-53

The Orioles captured the first-ever American League East championship in the first season following the division of the American League. They finished first with a record of 109 wins and 53 losses, 19 games ahead of the eventual world champion Detroit Tigers.

After the regular season, the Orioles faced the Minnesota Twins in the first American League Championship Series. They defeated the Twins in five games in the 1969 ALCS, but the New York Mets, who had won the National League, defeated them in the World Series. The team was led by Earl Weaver, and Memorial Stadium served as their home pitch.

7. 1927 | New York Yankees: 110-44

With a final record of 110-44-1, the team won their fifth pennant, finished 19 games ahead of the Philadelphia Athletics, and finished the entire season tied for first or better. Miller Huggins was the manager of the team.

The Yankees played at Yankee Stadium. They also defeated the Pittsburgh Pirates to win the 1927 World Series. This Yankees team is regarded as the greatest baseball team in MLB history and was known for its feared lineup, "Murderers' Row."

6. 1909 | Pittsburgh Pirates: 110-42

The 1909 Pittsburgh Pirates season was the franchise's 28th, and it was also the year they won their first World Series against the Detroit Tigers and the National League pennant with a record of 110-42. The Pirates scored the most runs in the majors, led by outfielder-manager Fred Clarke and shortstop Honus Wagner.

Wagner was league-leading in terms of batting average, on-base percentage, slugging percentage, and runs batted in. The Pirates still hold the team record for victories with 110, which they achieved on October 5, when they defeated the Cincinnati Reds 7-4 in muddy conditions. It is the best regular season win percentage by a World Series champion team.

5. 2022 | Los Angeles Dodgers: 111-51

The Dodgers' illustrious run of postseason appearances and NL West championships continued in 2022, marking another high point in the team's illustrious history. With their predecessors winning at least 104 games three times in the previous four full seasons, the 2022 Dodgers had a high standard to meet.

The Dodgers survived some significant pitching injuries despite losing Corey Seager and Max Scherzer to free agency (but signing Freddie Freeman). They began to distance themselves from their divisional rivals a year after the Giants won 107 games to dethrone them from their usual top spot.

4. 1954 | Cleveland Indians: 111-43

The 1954 Cleveland Indians progressed to the World Series for the first time in six years. In the history of the franchise, it was the team's third American League championship. The Indians' 111–43 record is the all-time record for winning percentage by an American League team (.721), as this was before 162 games were played in a season.

For over 60 years, Cleveland was the only team in Major League Baseball to have gathered two different 11-game winning streaks within the same season. This was until the Toronto Blue Jays accomplished the rare feat during the 2015 regular season.

3. 1998 | New York Yankees: 114-48

The 1998 New York Yankees season marked the franchise's 96th campaign. The team finished the regular season with a 114-48 record, setting a franchise record and is widely regarded as one of the greatest in baseball history.

Until 2001, when the Seattle Mariners won 116 games in the regular season against 46 losses, these Yankees held the American League record for wins in a season. Additionally, it saw Yankees pitcher David Wells pitch the league's 15th perfect game. Joe Torre was in charge of New York.

2. 2001 | Seattle Mariners: 116-46

They tied the major league record for victories set by the 1906 Chicago Cubs with a final record of 116-46 (.716) while also breaking the record for victories by an American League team. A record number of games were won by a margin of four runs or more in 59 of those victories, setting a new high. Additionally, they ranked first in the majors for runs scored and runs allowed.

Ichiro Suzuki, a Japanese outfielder who led the league in batting average and won both the American League Rookie of the Year and AL MVP awards in 2001, made his Major League debut that year. The Mariners also hosted the All-Star Game for the second time that season.

1. 1906 | Chicago Cubs: 116-36

The 1906 Chicago Cubs season marked the franchise's 35th year, and since then, they have held this MLB team record of all-time. Led by player-manager Frank Chance, the team finished the season 116–36, 20 games better than the New York Giants, who finished in second place.

The team set a modern MLB record for wins with a.763 winning percentage in their 154-game season, with two ties. The 1906 Cubs is frequently regarded as the greatest MLB team not to win the World Series. In a major shock, the Chicago White Sox defeated the Chicago Cubs in that year's World Series.

Which team has the most wins in the MLB season in a row?

The 1916 New York Giants, currently based in San Francisco, hold the record for the longest winning streak in MLB history. The team won 26 straight games throughout the season, which is astonishing. Their winning streak began on September 7 and ended on September 30, putting them nearly an entire month undefeated.

The record for the most wins in the MLB season is held by some great teams that have existed for decades. Most of these teams have been able to perform year in and year out due to their supportive officials and team base.
