Now that the first round is in the books, USOpen.org is tallying up the numbers.
129: American Alycia Parks tied the record for the fastest recorded serve ever struck by a woman at the US Open when she cracked a 129 mph serve on Day 1 against Olga Danilovic.
3: Number of points that Nick Kyrgios won behind his serve during the third set of his loss to Roberto Bautista Agut in Round 1.
22: Novak Djokovic’s Grand Slam winning streak. The Serb is now six matches from becoming the first male player to win the Grand Slam since Rod Laver in 1969.
1: Number of Top 10 seeds that didn’t make it through to the second round–No.9-seeded Pablo Carreno Busta was the only first-round casualty.
26: Length, in minutes of the fifth set tiebreak between Andreas Seppi and Marton Fucsovics on Day 2. Seppi won it, 15-13.
8: Number of comebacks from two sets down in the first round on the men’s side.
0-13: After his first-round loss to 18-year-old American Zachary Svajda, Marco Cecchinato falls to 0-13 at Grand Slams other than Roland Garros (where he is 9-5).
8: Number of teenagers that have reached the second round at this year’s US Open. Carlos Alcaraz, Lorenzo Musetti, and Zachary Svajda on the men’s side; Maria Camila Osorio Serrano, Clara Tauson, Emma Raducanu, Leylah Fernandez and Coco Gauff on the women’s side. If you’re scoring at home, the last teenager to win a US Open’s singles title was Bianca Andreescu in 2019.
16-0: Djokovic remains undefeated in first-round matches at the US Open. He has not won the title since 2018, however.

86: Number of Grand Slam victories achieved by Spain’s Carla Suárez Navarro at the major level. Suarez Navarro, who lost her final Grand Slam match to American Danielle Collins, didn’t add to that number in New York, but she may have achieved her greatest victory by returning to the tour in 2021 after overcoming Hodgkin’s Lymphoma.
49: Number of aces fired by South Africa’s Kevin Anderson during his first-round victory over Jiri Vesely. The 2017 US Open runner-up is the tournament’s ace leader through one round.
