Chicago got a rare September-style question in mid-August: what if the White Sox and Cubs both keep pushing long enough to meet in the World Series? On Monday at Wrigley Field, Bradford Doolittle tracked that possibility and found the odds for a White Sox-Cubs Fall Classic were about 63-to-1.
Doolittle’s new tracking tab logs daily simulation results and counts every time the two Chicago clubs show up together at the end of the bracket. His point was simple enough to read in one line and hard enough to ignore: when the White Sox and Cubs took the field Monday, both were being treated as contenders because either one could still reach October and turn a season into a shot at the Fall Classic. That is why the search interest is there now, on Aug. 17, with a three-game mid-August series starting and Chicago baseball fans suddenly looking at a matchup that feels both local and almost impossible.
The historical case behind it is thin. Since 1901, there have been only 11 seasons in which both Chicago clubs were in the contender class at the same time, a rate Doolittle put at 9% across 126 seasons. By his count, the White Sox were contending without the Cubs in 29 seasons, or 23%, while the Cubs were contending without the White Sox in 32 seasons, or 25%. In 54 seasons, or 43%, neither team was getting it done. That makes the current overlap notable before a single pitch is thrown in October, because the clubs are not just good at the same time; they are good at the same time in a city that almost never sees that happen.
Even so, the numbers keep their distance from the dream. At their reported apex, the chance of a White Sox-Cubs World Series was still about 63-to-1, which is why Doolittle’s tab matters more as a daily gauge than as a promise. The most recent reminder of how rare this is sits in history itself: there have been just three back-to-back dual-contention stretches, and the first began with the 1906 World Series and carried into 1907. That is the benchmark this moment has to clear, and it is a high one.
The next thing readers should watch is simple: whether both teams can hold their place long enough for the simulations to keep the matchup alive. For now, the story is not that Chicago has a World Series preview. It is that, on Aug. 17, both sides of town were still in the race, and the math said the same thing history has said for more than a century — possible, yes, but still a long shot.
