It's time once again for the Chaos Slam.
None of tennis' biggest tournaments boast the sheer unpredictability of the US Open. In the past nine years, 13 different men and 15 different women have reached the finals -- only Novak Djokovic, Rafael Nadal, Naomi Osaka and Serena Williams have done it multiple times in that span -- and seven different men and eight women have won the title. There's evidently something about the buzz of New York (or maybe it's just the humidity) that brings out both the best and the weirdest moments the sport has to offer.
