The St. Louis Browns were a Major League Baseball team that originated in Milwaukee, Wisconsin, as the Milwaukee Brewers. A charter member of the American League (AL), the Brewers moved to St. Louis, Missouri, after the 1901 season, where they played for 52 years as the St. Louis Browns.

After the 1953 season, the team moved to Baltimore, Maryland, where it became the Baltimore Orioles. The last two surviving former St. Louis Brown players, Ed Mickelson and Billy Hunter, died only six days apart on June 27 and July 3, 2025 respectively.

The St. Louis Browns had an overall win–loss record of during their 52 years in St. Louis. They were the least successful of the eight charter members of the American League, winning only one pennant and finishing fifth or worse 40 times.

The St. Louis Browns are represented by two players in the National Baseball Hall of Fame, Bobby Wallace and George Sisler.

Before 1902 In the late 19th century, the team was formed as the Milwaukee Brewers in the Western League. For the 1900 season, the Western League was renamed the "American League", and in 1901, league president Ban Johnson declared it a major league.

The team was originally owned by Milwaukee lawyers Matthew and Henry Killilea. As a minor league team, the Brewers had usually fielded subpar teams until Connie Mack became manager in 1894. The Killileas were among the poorer owners in the league, and did not have the resources to take advantage of the large number of National League players transferring to the American League. Of the 100 frontline players who switched leagues, only three signed with the Brewers. When Mack transferred to the Philadelphia Athletics at Johnson's behest as manager and part-owner, one of the three players who jumped to the Brewers, Hugh Duffy, became player-manager.

Johnson knew the Brewers could not be viable in Milwaukee, and originally intended to move them to St. Louis, a larger market. At the time, St. Louis was the fourth-largest city in the nation, while Milwaukee was the 15th. However, Matthew Killilea persuaded Johnson to give the Brewers what amounted to a one-year trial in Milwaukee, saying that he would agree to move to St. Louis if the team didn't make a good account of itself that year. Due to a lack of talent, the Brewers made a wretched showing. They never recovered from an 0–5 start, and crumbled to last place for good on June 30. They finished 48–89, the worst record in baseball, 35.5 games behind the pennant-winning Chicago White Sox. The team had additionally struggled with extended absences from Killilea, who spent most of the season battling tuberculosis and died on July 27. Henry was forced to become operating head of the team.

Under the circumstances, a move to St. Louis seemed a foregone conclusion. At a league meeting in Chicago, the Killileas requested and received permission to move. Soon after moving, the team changed its name to the Browns, a reference to the original name of the St. Louis Cardinals, who were known from the 1880s until 1900 as the Brown Stockings. Johnson then set about finding local ownership for the team, and found it in a syndicate headed by an old friend from his days as a sportswriter, Kansas City carriage maker Robert Hedges, who moved to St. Louis soon after the purchase closed. Hedges became team secretary while ceding the presidency to St. Louis businessman Ralph Orthwein. However, Hedges was the undisputed head of the franchise long before taking the presidency himself in 1903. He built a new park on the site of the original Browns' former venue, Sportsman's Park.

1902–1921

In their first season in St. Louis, the Browns finished second under manager Jimmy McAleer, five games behind Philadelphia. This was mainly because Hedges and McAleer persuaded six Cardinals to transfer to the Browns. They looked to become even more powerful in 1903 when Hedges signed New York Giants ace Christy Mathewson to a deal that would have paid him almost four times what he was earning in New York. However, as part of the settlement that ended the war with the National League, Hedges and Mathewson tore up the contract. Years later, Hedges said that while he knew he was likely giving up a pennant by relinquishing Mathewson to the Giants, it was more important to bring peace to the game.

Although the Browns had only four winning seasons from 1902 to 1922, they were very popular at the gate during their first two decades in St. Louis. They trounced the Cardinals in attendance; in 1908, for instance, they attracted four times as many fans as the Cardinals. Pitcher Barney Pelty was a workhorse for the Browns, and a member of their starting rotation from 1904, when he pitched 31 complete games and 301 innings, through 1911.Baseball in Saint Louis 1900-1925 - Steve Steinberg In 1909, the Browns rebuilt Sportsman's Park as the third concrete-and-steel park in the major leagues.

During this time, the Browns were best known for their role in the race for the American League batting title. Ty Cobb took off the last game of the season, believing that his slight lead over Nap Lajoie, of the Cleveland Naps, would hold up unless Lajoie had a near-perfect day at the plate. However, the Browns players decided to help Lajoie win the title over the unpopular Cobb. Browns' manager Jack O'Connor went along with the plan, since the game would have no bearing on the pennant race.Bio of Robert Hedges at Society for American Baseball Research O'Connor ordered rookie third baseman Red Corriden to play on the outfield grass. This all but conceded a hit for any ball Lajoie bunted. Lajoie bunted five straight times down the third base line and made it to first easily. On his last at-bat, Lajoie reached base on an error – officially giving him a hitless at-bat. O'Connor and coach Harry Howell tried to bribe the official scorer, a woman, to change the call to a hit – even offering to buy her a new wardrobe.

Cobb won the batting title by just a few thousandths of a point over Lajoie. But it was later reported that one game may have been counted twice in the statistics, and there were rumors about the attempted bribery, causing a scandal about the rankings. After news broke of the scandal, a writer for the St. Louis Post claimed: "All St. Louis is up in arms over the deplorable spectacle, conceived in stupidity and executed in jealousy." The resulting outcry triggered an investigation by Johnson. At his insistence, Hedges fired O'Connor and Howell; both men were informally banned from baseball for life.

After several pedestrian seasons, Hedges hired former Browns catcher Branch Rickey as business manager (de facto general manager) midway through the 1913 season, and made him manager as well in September. Although Rickey had been a mediocre player at best, he had a keen eye for spotting talent. His greatest find was George Sisler, who had played for Rickey at Michigan. They fell back to sixth in 1915, but won 79 games in 1916, their first winning record in eight years.

In , as part of the settlement that ended the war with the Federal League, Hedges sold the Browns to refrigeration magnate Philip DeCatesby Ball, who had owned the defunct league's St. Louis Terriers. Concluding that Rickey's talents were better suited to the front office, he named Fielder Jones as manager, while Rickey remained de facto general manager. Under Ball's early tenure, the club had its first sustained period of success on the field; they were a contender for most of the early 1920s.

However, analysts think Ball made a series of blunders that would ultimately doom the franchise. Shortly after buying the team, he allowed Rickey to accept the presidency of the Cardinals. When Johnson got wind of this, he told Ball in no uncertain terms that Rickey could not be allowed to go to the National League. However, since Rickey had a signed contract, Ball was only able to keep Rickey on his payroll for another 24 hours; Rickey was replaced by Bob Quinn. Four years later, Ball allowed the Cardinals to move out of dilapidated Robison Field and share Sportsman's Park with the Browns. Rickey and owner Sam Breadon used the proceeds from the Robison Field sale to build baseball's first modern farm system. This effort eventually produced several star players who brought the Cardinals more drawing power than the Browns.

1922–1940

The 1922 Browns excited their owner by almost beating the Yankees to a pennant. The club was boasting the best players in franchise history, including future Hall of Famer George Sisler and an outfield trio of Ken Williams, Baby Doll Jacobson, and Jack Tobin, who batted .300 or better from 1919 to 1923 and in 1925. In 1922, Williams became the first player in Major League history to hit 30 home runs and steal 30 bases in a season, something that would not be done again in the Majors until .

The following year, they crumbled to fifth, partly because Sisler missed the entire season due to sinus problems. At the same time, Ball, already a very hands-on owner, became even more so after Quinn left to buy the Boston Red Sox.

Ball confidently predicted that there would be a World Series in Sportsman's Park by . In anticipation, he increased the capacity of his ballpark from 18,000 to 30,000. There was a World Series in Sportsman's Park in  – but it was the Cardinals who took part, upsetting the Yankees. Meanwhile, the Browns slumped to seventh in the American League. More importantly, the Cardinals outdrew the Browns by more than 400,000. St. Louis had been considered a "Browns town" until then; as late as 1925, the Browns outdrew the Cardinals by more than 50,000. After their 1926 Series victory, however, the Cardinals dominated St. Louis baseball, while still technically tenants of the Browns. Meanwhile, the Browns rapidly fell into the cellar. They had only two winning records from 1927 to 1943, including a 43–111 mark in that is still the worst in franchise history. As a measure of how rapidly St. Louisians shifted to the Cardinals, the Browns set a franchise record for attendance in 1922, attracting over 712,000 people. This figure would never be approached again for the rest of the franchise's tenure in St. Louis, and would remain the franchise record until 1954, the team's first year in Baltimore.

Ball had previously spent lavishly on the Browns, but gradually cut that spending to the bare minimum. He died in 1933, and his estate ran the team for three years, with Ball's former right-hand man Louis Von Weise as team president. The Ball estate mostly left the baseball side to player-manager and former Cardinals great Rogers Hornsby, whom Ball had hired in one of his last acts before his death. However, the Ball estate withheld badly needed capital that could have been used to get better players. Attendance sagged to the point that the other American League teams could not meet their travel expenses. In 1936, Rickey helped broker a sale to investment banker Donald Lee Barnes. Cardinals treasurer Bill DeWitt, Barnes' son-in-law, bought a minority stake in the Browns and became the team's general manager. To help finance the purchase, Barnes sold 20,000 shares of stock to the public at $5 a share, an unusual practice for a sports franchise. Soon afterward, he fired Hornsby after learning he was placing bets on horse races during games.

War era By 1941, Barnes was convinced he could never make money in St. Louis. After interests in Los Angeles approached him about buying a stake in the team, he asked AL owners for permission to move there for the 1942 season. Los Angeles was already the fifth-largest city in the United States, and was larger than any major-league city except New York, Chicago, Philadelphia and Detroit.
