Danielle Collins (11) against Caroline Dolehide
Danielle Collins is playing her final US Open after announcing her retirement from professional tennis earlier this year, and this season has been one of the best of her career.
Dolehide, on the other hand, is probably tired of seeing her fellow countrywomen at Grand Slam tournaments. She has lost to Coco Gauff, Collins and Gauff at each of the three majors this year.
Jelena Ostapenko (10) against Naomi Osaka (WC)
This is one of the most anticipated first-round matches at the US Open. Naomi Osaka is a two-time champion in New York and is trying to find her form on the hard courts. Jelena Ostapenko reached the quarterfinals of Wimbledon in 2024, her best result at the US Open was the quarterfinals in 2019.
This is the second meeting between the two, with Osaka winning the first match at the 2016 French Open, and it promises to be a power tennis spectacle.
Dusan Lajovic vs Daniil Medvedev (5)
Daniil Medvedev has become a crowd favorite at the US Open. After drawing loud boos at the start of the 2019 tournament, Medvedev reached the final this year, won the title in 2021 and finished runner-up to Novak Djokovic last year.
Medvedev had a bumpy hard court season in the summer, with first round losses in Toronto and Cincinnati. Dusan Lajovic is now hoping for a surprise, as the Serb never made it past the second round in New York.
Bianca Andreescu (WC) versus Jasmine Paolini (5)
This is another popcorn first-round match. It is the third consecutive Grand Slam tournament in which Bianca Andreescu and Jasmine Paolini have faced each other, with the Italian winning both matches.
Paolini reached the finals of both the French Open and Wimbledon, while Andreescu is trying to return to the form she had five years ago when she won the US Open.
Lorenzo Sonego vs Tommy Paul (14)
Tommy Paul enters the US Open having won an Olympic bronze medal in men’s doubles, but since playing on clay at the Olympics, Paul has struggled on hard courts.
He lost in the second round of Canada and the first round of Cincinnati. Paul’s opponent, Lorenzo Sonego, won the fourth ATP Tour title of his career in Winston-Salem, NC, the week before the US Open.
