The US Open is underway as the final grand slam of the year is up and rolling in Flushing, NY and we have your Day 2 guide to betting on the tournament.
The 2025 US Open continues in New York City on Monday, August 25, for Day 2 at Flushing Meadows. The fourth and final Grand Slam of the year is where legacies are forged and underdogs make their move, but it's also a major event for those looking for the best bets and tennis predictions. The tournament runs through to Championship Sunday on September 7.
Day 1 saw only one major upset, with 13th seed Daniil Medvedev knocked out by unseeded Frenchman Benjamin Bonzi in 5-sets. Novak Djokovic (7) and Brandon Nakashima (30) advanced, though, as did one of our pre-tournament value plays Emma Raducanu, along with top-seed Aryna Sabalenka.
