UPDATE: The Royals won 2-1 to sweep the Orioles and win their first pennant since 1985.
The Kansas City Royals are one win away from the World Series. Take a moment to let that sink in, then let's take a look at how often teams leading a best-of-seven series 3-0 finish the sweep.
The Royals are the 34th team in major league history to go up 3-0 in a best-of-seven postseason series. 27 of the first 33, a whopping 81.8 percent, completed the sweep in Game Four.
UPDATE: With the KC victory, teams up 3-0 are now 28-6 in Game Four, good for an amazing .824 winning percentage!
Of the six that managed to stay alive for another game, three were put away in the fifth game. The 1998 Braves won two games in San Diego to become the first team to force a Game Six after being down 3-0, but they lost. A year later they were on the other side when the Mets came back to push it to six games, but an Andruw Jones walk-off walk won the pennant, 4-2. The only team to force a Game Seven after losing the first three games is the 2004 Red Sox, who finished the job with a 10-3 thrashing of the rival Yankees in the Bronx.
