List of teams to overcome 3–1 series deficits
The following is the list of teams to overcome 3–1 series deficits by winning three straight games to win a best-of-seven playoff series. In the history of major North American pro sports, teams that were down 3–1 in the series came back and won the series 53 times, more than half of them were accomplished by National Hockey League (NHL) teams. Teams overcame 3–1 deficit in the final championship round eight times, six were accomplished by Major League Baseball (MLB) teams in the World Series. Teams overcoming 3–0 deficit by winning four straight games were accomplished five times, four times in the NHL and once in MLB.
The Boston Red Sox of MLB and the Vancouver Canucks of NHL each overcame 3–1 deficits the most at three times, while the Washington Capitals of NHL blew 3–1 leads the most at five times, followed by the St. Louis Cardinals of MLB at four times (including twice in the World Series). Two teams have overcome 3–1 deficits multiple times in the single playoffs: the Kansas City Royals of MLB in 1985 and the Minnesota Wild of the NHL in 2003. Two teams have also overcome 3-1 deficits in a single playoffs only to have the favor returned to them: the Golden State Warriors of the NBA in 2016, and the Vancouver Canucks of the NHL in 2003.
Major League Baseball
MLB teams have overcome 3–1 deficits 13 times (including 3–0 deficit 1 time), six of which occurred in the World Series. This does not count the 1903 World Series, in which the Boston Americans (later known as the Red Sox) came back from down 3 games to 1 against the Pittsburgh Pirates, as that series was a best-of-nine series.
National Basketball Association
NBA teams have overcome 3–1 deficits 11 times, only one of which occurred in the NBA Finals. The NBA is the only sport with a seven game playoffs series where no team has ever overcome a 3–0 deficit.
National Hockey League
NHL teams have overcome 3–1 deficits 29 times (including 3–0 deficits 4 times), only one of which occurred in the Stanley Cup Finals.
