The History of the Boston Red Sox: Every Era, from the First Season to Today
The Boston Red Sox story in eras, from the 1901 Americans and five early titles through the long drought, four Game 7 heartbreaks and the four championships won since 2004.
The Boston Red Sox have played every season of the American League, which began in 1901, and the historical record through 2025 shows a record of 10,044 wins and 9,336 losses, a .518 winning percentage. They have won 14 pennants and nine World Series. The way those nine titles are spread out explains why the club's history has the reputation it does: five came in the first 16 years, then none for 86 years, then four in 15 seasons.
That gap is the spine of the story. Between the 1918 title and the 2004 one, Boston reached the World Series four more times and lost all four in seven games. Add the near misses in the pennant races, the great hitters who never won a ring and a ballpark that is now more than a century old, and the Red Sox become the club that baseball fans most often describe in terms of narrative rather than numbers. This article tries to keep both: the narrative, and the numbers behind it.
What follows takes the franchise era by era, using the season records, pennant and title years, managers and club leaders in the historical data. For the same club told through its greatest players or its best teams, see the best players in Boston Red Sox history and the best seasons and every October run.
The Americans, 1901 to 1907
The club that became the Red Sox was one of the eight charter members of the American League in 1901. It was called the Boston Americans for its first seven seasons, and it played at the Huntington Avenue Grounds, which was its home from 1901 to 1911. Jimmy Collins, a third baseman who later reached the Hall of Fame, was the player-manager for the first six seasons and compiled a 455-376 record in 842 games as manager.
The pitching staff was built around Cy Young, who joined in 1901 and won 192 games for Boston through 1908, tied with Roger Clemens for the most in club history. Young's 38 shutouts for the club are also tied with Clemens at the top of the franchise list. He had already pitched 11 seasons in the National League before he arrived, and his career total of 511 wins is covered in our profile of Cy Young.
Boston won the pennant in 1903 and met the Pittsburgh Pirates in what is counted as the first modern World Series, a best-of-nine format. The Americans won it five games to three. They took the pennant again in 1904, but the National League champion New York Giants declined to play a World Series that year, so the franchise has a 1904 pennant and no 1904 title. The series resumed in 1905 and has been played every season since, apart from the 1994 strike year.
The club's fortunes dropped quickly afterwards. In 1906 Boston went 49-105, a .318 winning percentage and one of the five worst seasons in franchise history. The name changed to the Red Sox in 1908, and it has not changed since.
Fenway Park and the first dynasty, 1912 to 1918
Fenway Park opened in 1912, and its first season was the club's best to that point. Boston went 105-47, a winning percentage of .691 that remains the highest for any full season in the franchise's history, and beat the New York Giants in a close World Series, four games to three. Tris Speaker won the American League's Chalmers Award, the forerunner of the MVP, that season, and the outfield of Speaker, Harry Hooper and Duffy Lewis was one of the most admired of its time. Hooper's 300 stolen bases for the club remain Boston's career record, with Speaker second at 267.
Smoky Joe Wood was the other star. Wood's 1.99 career earned run average for Boston is the best of any pitcher with 1,000 innings for the club, narrowly ahead of Cy Young's 2.00. He won 117 games for the franchise before arm trouble ended his run as a front-line pitcher.
Boston won again in 1915 (a 4-1 series over the Philadelphia Phillies) and in 1916 (4-1 over Brooklyn, a club that is today's Los Angeles Dodgers). Bill Carrigan managed those two teams. In 1918 the Red Sox beat the Chicago Cubs four games to two in a season shortened by the First World War. The pitching staff by then included a young left-hander named Babe Ruth, whose 2.19 ERA with Boston is fourth on the franchise's list for pitchers with 1,000 innings. He also played the outfield part of the time, and that arrangement gave Boston its last title of the 20th century.
That fact was not obvious at the time. That made five titles in the 16 seasons from 1903 through 1918, and nobody in Boston at the time would have predicted an 86-year wait for the sixth.
The Frazee years and the long fall, 1919 to 1933
The change came with the sale of Babe Ruth to the New York Yankees in the winter of 1919-20 by the owner, Harry Frazee. The price and the reasons have been argued for a century, and the popular explanation, that Frazee needed money for his theater productions, is only part of a financial picture that historians still debate. What is not in dispute is what happened afterwards. Ruth, who had hit 29 home runs for Boston in 1919, became a transformative hitter for the Yankees, who won their first pennant in 1921 and their first World Series in 1923. The Red Sox declined.
The sheet of worst seasons by winning percentage makes the decline plain. Boston lost 105 games in 1925 (47-105), 107 in 1926 (46-107), 103 in 1927 (51-103), and then 111 games in 1932 (43-111), the worst record in club history. The crowds shrank with the team. The best season attendance at the first version of Fenway Park, from 1912 to 1933, was 597,096, less than the 668,965 the old Huntington Avenue Grounds had once drawn.
That trade is the start of the Boston and New York rivalry. For the other side of the story, see the history of the New York Yankees.
Yawkey, Cronin and Ted Williams, 1934 to 1960
Tom Yawkey bought the club in 1933 and spent heavily, acquiring stars such as Lefty Grove, Jimmie Foxx and Joe Cronin. Fenway Park was rebuilt after a fire, and the version that fans know today dates from 1934. Its left-field wall, about 37 feet tall and painted green, became the Green Monster. The park is small and odd: the site's reference data gives a left-field line of 310 feet, a center-field distance of 390 feet, the deepest of its five listed points, and a right-field line of only 302 feet.
Cronin, a Hall of Fame shortstop, became player-manager in 1935 and managed the club through 1947. His 1,071 wins as manager are the most in franchise history, and his 2,007 games are the most for any Boston manager. Foxx, who won the MVP award in 1938, is covered in our profile of Jimmie Foxx.
But the great story of the era was Ted Williams, who arrived in 1939. Williams hit .406 in 1941, the last major leaguer to reach .400, and led the league in walks again and again. He lost years to military service in the Second World War and the Korean War, and still finished with 521 home runs, the most in Red Sox history, and 2,021 walks. His career average with the club, .344, is the best of any Boston hitter with 3,000 at-bats, and his career on-base percentage of .482 is the highest in major-league history among players with long careers.
The team won the 1946 pennant with a 104-50 record, its first since 1918, and lost the World Series to the St. Louis Cardinals in seven games. Williams, who won MVP awards in 1946 and 1949, hit .200 in that series. The deciding game is remembered for Enos Slaughter's dash from first base on a hit in the eighth inning, and for the long argument about whether Boston's shortstop Johnny Pesky held the relay throw. In 1949 the Red Sox went 96-58 and finished a single game behind the Yankees, losing the last two games of the season to them.
The Impossible Dream, Fisk and Bucky Dent, 1967 to 1978
The next pennant took 21 years. In 1967 a team that had finished ninth the season before won the American League by a single game, with Carl Yastrzemski winning the Triple Crown and the MVP award, and Jim Lonborg winning the Cy Young Award. The season was nicknamed the Impossible Dream. Boston lost the World Series to the Cardinals in seven games, with Bob Gibson winning three of them.
Yastrzemski's career at Fenway was long. His 3,419 hits, 1,844 RBI and 1,816 runs are all club records, and his 452 home runs are third on the franchise's list. He spent all 23 of his major-league seasons in Boston, the most of any player in the club's history.
The 1975 team was built on rookies Fred Lynn, who was Rookie of the Year and MVP, and Jim Rice. It beat the Oakland Athletics in three games in the American League Championship Series and faced the Cincinnati Reds in a World Series that is often ranked among the best ever played. Carlton Fisk's home run off the left-field foul pole to end Game 6 is one of the best-known moments in the sport. The Reds won Game 7. In 1978 Boston lost a one-game playoff to the Yankees after Bucky Dent's home run over the Green Monster, having held a large lead in the division in July.
Four Game 7 defeats, 1946 to 1986
Four World Series defeats in seven games is a pattern worth looking at on its own. The table lists them.
| Year | Opponent | Games | Note |
|---|---|---|---|
| 1946 | St. Louis Cardinals | 3-4 | First pennant since 1918 |
| 1967 | St. Louis Cardinals | 3-4 | The Impossible Dream |
| 1975 | Cincinnati Reds | 3-4 | Fisk's Game 6 home run |
| 1986 | New York Mets | 3-4 | Game 6 at Shea Stadium |
The 1986 team had Roger Clemens, who won both the Cy Young Award and the MVP award that year, and beat the California Angels in a seven-game ALCS after trailing three games to one. In the World Series against the Mets, Boston was within one strike of a championship in Game 6 and lost it on a ground ball that went through the legs of first baseman Bill Buckner. The Mets won Game 7. The other side of that series is in our history of the New York Mets.
Division titles, Pedro and the Yankees, 1988 to 2003
After the divisional split, Boston won the American League East in 1988 and 1990 and was swept by Oakland in both American League Championship Series (0-4 each time). A third division title came in 1995 with Mo Vaughn, who won the MVP award, but Cleveland swept the Division Series. The club reached the playoffs as a wild card in 1998, 1999, 2003, 2004 and 2005.
Pedro Martinez arrived from Montreal in a trade after the 1997 season and won the Cy Young Award in 1999 and 2000, while Nomar Garciaparra, the 1997 Rookie of the Year, hit .323 for the franchise. In 1999 Boston came back from two games down to beat Cleveland 3-2 in the Division Series and then lost to the Yankees 1-4 in the ALCS.
The sharpest wound came in 2003. Boston and New York met in a seven-game ALCS, with the Red Sox losing 3-4 when Aaron Boone's home run in the 11th inning of Game 7 ended it. Manager Grady Little had left Martinez in the game in the eighth inning with a lead, a decision that cost him the job.
2004 and the three titles that followed
The 2002 sale of the club to a group led by John Henry brought Theo Epstein as general manager, and in 2004 the club finally got over the hump. Terry Francona, in his first season in Boston, took the Red Sox into the ALCS against the Yankees. New York won the first three games. Then Boston won four in a row, the only team in baseball history to take a best-of-seven series after losing the first three. David Ortiz's walk-off hits in Games 4 and 5 and Dave Roberts's stolen base in the ninth inning of Game 4 are the plays that fans remember most. The Red Sox then swept St. Louis four games to none for the franchise's first title since 1918.
Francona's tenure produced a second title in 2007, when Boston swept Colorado in the World Series after beating Cleveland 4-3 in the ALCS. His 739 wins and 1,286 games rank second to Cronin in club history. Ortiz, the designated hitter, finished with 483 home runs and 1,530 RBI for the Red Sox, second only to Williams in homers and third in RBI behind Yastrzemski and Williams. Dustin Pedroia won the Rookie of the Year award in 2007 and the MVP award in 2008.
A third title in the Ortiz era came in 2013, after the Boston Marathon bombings in April, when the Red Sox beat Detroit 4-2 in the ALCS and the Cardinals in the World Series. John Farrell was the manager, and the team won its first division title since 2007. The World Series was clinched at Fenway Park, the first time Boston had won a title at home since 1918.
Alex Cora, 2018 and the years since
The fourth title of the century came in 2018 under Alex Cora. Boston won 108 games, 108-54, which is the most wins in franchise history, though the 1912 team's .691 winning percentage remains higher. Mookie Betts was the American League MVP. The Red Sox beat the Yankees 3-1 in the Division Series, the Astros 4-1 in the ALCS and the Dodgers 4-1 in the World Series.
Cora was dismissed in January 2020 after the investigation into sign stealing by the Astros, with whom he had been the bench coach in 2017, and returned for 2021. He is third on the club's list of games managed, with 609 wins and 1,133 games through 2025. In 2021 the Red Sox won the wild-card game against the Yankees, beat Tampa Bay 3-1 in the Division Series and lost the ALCS to Houston 2-4. In 2025 they again reached the wild-card round but lost to the Yankees in three games, 1-2.
The franchise by the numbers
The leaders in the historical data give a snapshot of the club's identity, which has been about hitters more than pitchers, and the left-field wall more than the outfield.
| Category | Leader | Total |
|---|---|---|
| Home runs | Ted Williams | 521 |
| Hits | Carl Yastrzemski | 3,419 |
| RBI | Carl Yastrzemski | 1,844 |
| Stolen bases | Harry Hooper | 300 |
| Wins | Roger Clemens and Cy Young | 192 each |
| Strikeouts | Roger Clemens | 2,590 |
| Saves | Jonathan Papelbon | 219 |
Tim Wakefield, the knuckleball pitcher, won 186 games and struck out 2,046 batters for the club, third in wins and second only to Clemens in strikeouts. Wade Boggs hit .338 for the club. Boston players have won 12 Most Valuable Player awards (counting Speaker's Chalmers Award), from Speaker in 1912 to Mookie Betts in 2018, and seven Cy Young Awards, won by four pitchers: Jim Lonborg, Clemens, Martinez and Rick Porcello.
Common questions
How many World Series have the Red Sox won? Nine: 1903, 1912, 1915, 1916, 1918, 2004, 2007, 2013 and 2018. They have also lost four World Series, all in seven games (1946, 1967, 1975 and 1986).
What was the curse of the Bambino? It was a nickname, coined in a 1990 book title and popular in the 1990s, for the 86-year stretch without a title that followed the sale of Babe Ruth to New York. Nothing about it was supernatural, and the gap had ordinary causes, among them the narrow misses recorded above. The club was also the last in the majors to add a Black player, in 1959.
Where does the club play? Fenway Park, which opened in 1912, is the oldest ballpark in the major leagues. Our Fenway Park guide covers its dimensions and how it plays.
Who is the best player in club history? Williams and Yastrzemski dominate the lists. Williams wins on rate statistics and Yastrzemski on volume, and Pedro Martinez and Clemens are the main candidates among pitchers.
