Red Sox Beat Yankees for 15th Straight Win, Setting 1946 Franchise Record

Q: Does a record streak or a championship title ultimately define a team's place in baseball history?

A championship title ultimately defines a team’s place in baseball history more than a record streak. The 1946 Red Sox are a strong example. Their 15-game winning streak was extraordinary, remains the longest in franchise history as of 2026, and helped turn them into a national story. It showcased their power, depth and resilience, and it still matters because such streaks are rare. But the team is remembered even more for what followed: a 104-50 season, an American League pennant, and a seven-game World Series loss to St. Louis. The streak is part of the story; the absence of a title is the larger historical verdict. That pattern holds across baseball history. Winning streaks create momentum, headlines and enduring franchise records, but championships are the sport’s final measure. Teams such as the Yankees are defined primarily by title totals, not by regular-season streaks. Dynasties are built on championships, and even great regular-season runs are usually judged by whether they ended with a World Series trophy. That does not make streaks unimportant. They can capture a city, reshape a season and become part of a club’s identity for decades, as the 1946 Red Sox have. They often serve as evidence that a team was special. But if history must choose one standard, it chooses the championship, because that is the achievement that settles legacy beyond debate.

Boston’s 15th straight victory came in a 6-5 comeback over the Yankees on May 10, 1946, after Joe DiMaggio’s grand slam erased an early Red Sox lead before Rudy York and Dom DiMaggio drove in the decisive seventh-inning runs.
64,183 fans watched the key test in New York, where manager Joe Cronin pulled Joe Dobson after the homer and reliever Earl Johnson allowed just one hit over five shutout innings to seal the streak.
The run to 15 included a sweep of the defending champion Tigers, two wins over Cleveland, three over the Browns, three over the White Sox, three over the Athletics and one earlier win over New York.
The streak gave Boston a rare national surge of support in a season when Ted Williams, Johnny Pesky, Bobby Doerr and company were emerging as a pennant threat after years of near misses.
