Alright Yankees fans, this is where your team shines, but you already knew it, didn't you? Not only do the Yanks have by far the most World Series wins of any team since the series began in 1903, but also the longest streak of World Series victories, too.
The Yankees' five-year-long record-setting streak occurred during the seasons spanning 1949-53. The next closest team is the Oakland Athletics, which went three straight from 1972-74 [source: MLB.com]. The rosters of this era read like the Super Friends of mid-century pro baseball, with names like Yogi Berra, Phil Rizzuto, Joe Collins, Billy Martin, Joe DiMaggio and Whitey Ford.
As for longest winning streaks during a single playoff season, this is the set of stats that Boston Red Sox fans just won't let Yankees fans forget. Not only did the 2004 Red Sox stage the longest win streak of any playoff season, it also was one of the biggest comebacks in World Series history, too.
The story goes like this: The Yankees had the Sox down three games to zero in a seven-game American League series. Game three had been a 19-to-8 annihilation. The Yankees' sweeping advancement to the World Series seemed foregone. But in the fourth game, the Red Sox held on for 12 innings through the longest game of an American League Championship Series (it lasted more than five hours) for a 6-4 victory [source: Feinsand]. In the next game, the Red Sox battled back to tie the game in late innings, which led to another record run time (5:49 over 14 innings) and another win. Momentum had clearly swung in Boston's favor as the club charged through two more games to win its league. Boston followed up by sweeping the World Series against the St. Louis Cardinals. The team set the streak record at eight wins and became the first club to come back and win the World Series after being down 3-0 in League Championship play.
