Baseball teams are 6-26 in game four after losing the first three games of a seven game series. That’s pretty amazing. You would figure that the teams in the World Series should be pretty evenly matched, so the winning percentage should be closer to 50%. Even if you think the trailing team should only have a .400 winning percentage against the winning team, the 95% confidence interval would be 8 to 18 wins. Either winning the first three games indicate one team is much better than the other, or losing three in a row causes some psychological change that makes it tough to win game four.
Its after first losing the first three games. There should be a line drawn through the “first winning” part. This did make me click on the link, however.
I think the explanation is that this usually happens when one of the teams in the series is really much better than the other team (which generally is there as a fluke). The 2004 Red Sox in the LCS is as you would expect the big exception. Though oddly enough the Cardinals team they met in the World Series that year were also an exception.
