The Guardians beat the White Sox 6-4 on Wednesday. They need to win eight more games to finish with a higher winning percentage than the 1962 Mets (.250). Now the three generous estimates of their intrinsic winning percentage and probability of no more than 40 wins stand at:
Method | Intrinsic WPct | Probability of No More than 40 Wins |
95% Confidence Interval based on actual wins | 0.294 | 0.955 |
Replacement Level | 0.296 | 0.954 |
95% Confidence Interval based on Pythagorean wins (+8) | 0.352 | 0.883 |
Chicago only needs six more wins to finish with a better winning percentage than the 1916 Athletics. That team went 36-117, a .2353 winning percentage. If the White wind up 38-124, they would own a .2346 winning percentage, and set the modern record for lowest winning percentage in a season. Here are the probabilities for that happening:
Method | Intrinsic WPct | Probability of No More than 38 Wins |
95% Confidence Interval based on actual wins | 0.294 | 0.739 |
Replacement Level | 0.296 | 0.733 |
95% Confidence Interval based on Pythagorean wins (+8) | 0.352 | 0.558 |
They are almost certain to finish worse than the 1962 Mets, and only the most generous probability based on their bad luck gives then a 50/50 chance than of finishing ahead of the 1916 Athletics. In fact they are now favorites in every scenario to be the worst team of the modern era.
