These are the teams that have won the most consecutive games in a row in major league baseball history; they are the teams with the longest winning streaks in baseball history.
I have included all the teams that won at least 19 games in a row. The teams that won enough games in a row to make this list all had winning records well above .500 for the season, although most of these teams did not win the World Series.
Teams with Longest Winning Streaks in Major League Baseball History
1. 1916 New York Giants – 26 games
The 1916 New York Giants hold the record for the longest winning streak in MLB history, winning 26 games in a row. There was a tie game in the middle of the streak against the Pittsburgh Pirates that was never finished, probably due to darkness or rain.
The Giants’ record win streak began on Sept. 7, 1916, and ended with a defeat in the second game of a doubleheader on Sept. 30, 1916. All 26 games in the streak were played at home in the Polo Grounds.
The New York Giants were a “streaky” team in 1916. In addition to the record 26-game win streak, the team also had a winning streak of 17 games, and suffered losing streaks of eight and six games. The 1916 Giants went 86-66 on the year, and finished in fourth place in the National League.
T-2. 1935 Chicago Cubs – 21 games
The second-longest winning streak in baseball history belongs to the 1935 Chicago Cubs, who won 21 straight games from Sept. 4 to Sept. 28. The first 19 games of the streak were all at home in Wrigley Field. The Cubs then won three more games in St. Louis, before losing to the Cardinals in an 11-inning game on Sept. 28, 1935.
The 1935 Chicago Cubs finished the season with a 100-54 record, best in the National League. The Cubs lost the World Series to the Detroit Tigers in six games.
T-2. 1880 Chicago White Stockings – 21 games
The 1880 Chicago White Stockings, who became the Chicago Cubs in 1903, also won 21 games in a row. The winning streak lasted from June 2 to July 10. The first 10 games of the streak were on the road, and the remaining 11 wins were at home. The streak then ended in the first game of a road trip against the Cleveland Blues.
The 1880 Chicago White Stockings went 67-17 on the season. The team finished in first place in the National League. The World Series was not played in 1880, and was not officially played until the turn of the century.
T-4. 2002 Oakland A’s – 20 games
The 2002 Oakland A’s won 20 straight games, lasting from Aug. 13 to Sept. 6. The winning streak began with five wins at home, followed by 10 consecutive road wins, and concluded with five more home wins. The A’s then went on the road and lost to the Minnesota Twins on Sept. 6, 2002, ending their amazing run.
The 2002 Oakland A’s are a famous team because author Michael Lewis wrote his book “Moneyball” based mainly upon the team, and their general manager, Billy Beane. The 2002 A’s went 103-59 on the season, and won the American League West. The A’s lost to the Minnesota Twins in the ALDS in the playoffs.
T-4. 1884 Providence Grays – 20 games
The 1884 Providence Grays won 20 straight games from Aug. 7 to Sept. 9. Amazingly, pitcher Hoss Radbourn started all 20 games. He won 18 of them , all in a row. Radbourn finished the 1884 season with 59 wins, which is the record for most wins in a season by a pitcher.
The Grays team went 84-28 in 1884, finishing the season with the best record in the National League. After the season, in what was a forerunner to the modern World Series, the Grays were challenged to a best-of-three match by the New York Metropolitans, who were the best team that season in the rival American Association. The Grays won all three games, with Hoss Radbourn starting and completing all three wins.
T-4. 1884 St. Louis Maroons – 20 games
The St. Louis Maroons of the Union Association won 20 straight games during the 1884 season, the only year that the Union Association existed. The 20-game winning streak began with the first game of the season on April 20, and ended on May 24. The Union Association was considered second class by many in 1884, so take this win streak for what you will.
The 1884 St. Louis Maroons went 94-19, and won the Union Association by 21 games. After the Union Association folded, the Maroons moved to the National League, where they went just 36-72 in 1885.
T-7. 1947 New York Yankees – 19 games
The 1947 New York Yankees won 19-straight games from June 29 to July 18. Thirteen of the wins were on the road, and six were at home in Yankee Stadium. The 1947 Yankees went 97-57, winning the American League pennant. The Yankees then beat the Brooklyn Dodgers in seven games to win the World series.
T-7. 1906 Chicago White Sox – 19 games
The 1906 Chicago White Sox won 20 consecutive games from Aug. 2 to Aug. 25. The first 11 wins of the streak came at home, while the remaining eight were on the road. The White Sox played a scoreless tie game during this winning streak.
The 1906 Chicago White Sox finished in first place in the American League. The team went on to famously beat their cross-town rivals, the Chicago Cubs in the World Series in six games. The 1906 Chicago Cubs went 116-36, and still hold the major league record (120 or more games played) for the highest winning percentage in a season (.763).
