In March 1904, before the season had even started, New York Giants owner John T. Brush announced that his National League champions wouldn't play the American League pennant winner in a World Series. His manager, John McGraw, backed him. The Highlanders, Brush declared, were a "minor league" operation. The American League was beneath the Giants' dignity. It was an act of petty spite that backfired spectacularly -- the public outrage over the cancelled Series forced the two leagues to formalize the event as a permanent annual institution, creating the October tradition that has defined baseball ever since.
Brush's Grudge
The boycott wasn't really about the Highlanders' quality. It was about territory. The Giants had been New York's team since the 1880s. The Polo Grounds was their cathedral. When Ban Johnson placed an American League franchise in Manhattan -- the Highlanders, born from the ashes of the Baltimore Orioles -- Brush saw it as an invasion. Every fan who walked through the gates at Hilltop Park was a fan who might've been sitting in the Polo Grounds instead.
Brush and McGraw shared a history of antagonism toward the AL. Brush had been involved in the 1902 raid on the Baltimore Orioles, conspiring with McGraw to strip the franchise of its best players. McGraw had jumped from Baltimore to the Giants that same year, carrying with him a deep personal animosity toward Ban Johnson and everything the American League represented. For both men, refusing to play the AL champion wasn't just competitive strategy. It was ideological warfare.
The Timing
The boycott announcement came in March, when nobody knew how the season would unfold. Brush assumed the Highlanders would be mediocre -- a second-division team that wouldn't come close to a pennant. He could dismiss them as minor-league pretenders without much risk of embarrassment.
The 1904 season made Brush look foolish. The Highlanders won 92 games. Jack Chesbro won 41. New York was in first place as late as October 7. A franchise that Brush had called minor-league came within 1.5 games of the American League pennant, and if not for a wild pitch on October 10, they might've won it.
Even after Boston clinched the pennant instead of the Highlanders, Brush maintained the boycott. The Giants wouldn't play the American League champion -- any American League champion. The 1903 World Series, in which Boston's Americans had beaten Pittsburgh's Pirates in a thrilling eight-game set, wouldn't be repeated.
The Public Reaction
Fans were furious. The 1903 World Series had been a sensation -- proof that interleague competition could produce drama, revenue, and a genuine champion of champions. Cancelling the event denied players their Series bonus money. It denied fans the spectacle. And it denied baseball the legitimacy that came from crowning an undisputed champion.
Sportswriters condemned Brush's decision as petty and self-serving. The narrative wasn't complicated: a wealthy owner had sacrificed the fans' enjoyment to protect his ego and his market position. Brush had calculated that dismissing the AL would weaken it. Instead, his boycott generated sympathy for the American League and made the Giants look arrogant.
McGraw's involvement added another dimension. The Giants' manager had a personal grudge against Ban Johnson that dated back to his suspensions in Baltimore in 1901. For McGraw, the boycott was a chance to humiliate the man who'd humiliated him. But the public didn't care about McGraw's grudges. They cared about baseball.
The Permanent Fix
The backlash accomplished what Johnson and the AL had been trying to achieve since 1903: a formal agreement between the two leagues governing the World Series. Over the winter of 1904-1905, the National and American Leagues negotiated a compact that established the Series as an annual event with defined rules, scheduling, and revenue-sharing structures.
The agreement -- sometimes called the Brush Rules, in an ironic nod to the man whose boycott had made them necessary -- ensured that no owner could unilaterally cancel the Series again. The pennant winners would meet in October, period. The fans had demanded it. The players had demanded it. And the business of baseball required it.

What Brush Built by Accident
The irony is sharp enough to cut. Brush's boycott was designed to diminish the American League and assert the Giants' superiority. Instead, it created the formal structure that made the World Series permanent -- the single most important institution in American professional sports at the time. By refusing to play, Brush forced the leagues to negotiate a framework that guaranteed the Series would happen every year. His petty act of spite produced the opposite of what he'd intended.
The 1905 World Series went ahead without controversy. The Giants won it, beating the Philadelphia Athletics in five games. McGraw managed his team to a championship in the very event he'd tried to cancel the year before. Baseball had its annual tradition. The fans had their October. And John T. Brush's name is attached to the rules that made it all possible -- not because he wanted the Series, but because he'd tried to kill it.

Frequently Asked Questions
Why was there no World Series in 1904?
Giants owner John T. Brush and manager John McGraw refused to play the American League champion, calling the Highlanders a "minor league" operation. The boycott, announced in March 1904, held even after Boston rather than the Highlanders won the AL pennant. It's the only year since 1903 that the World Series wasn't played (excluding the 1994 strike-cancelled Series).
How did the 1904 boycott lead to the permanent World Series?
Public outrage over the cancelled Series forced the National and American Leagues to negotiate a formal agreement during the winter of 1904-1905. The resulting rules -- sometimes called the Brush Rules -- established the World Series as an annual event with mandatory participation by both pennant winners. The agreement created the institutional framework that has governed the Series ever since.
Did the Giants play in the 1905 World Series?
Yes. Under the newly formalized rules, the Giants played and won the 1905 World Series, beating the Philadelphia Athletics in five games. John McGraw managed the Giants to the championship in the very event he'd tried to cancel the previous year.
