He has three exits in the first and second rounds over his last four appearances in the Australian Open's main draw. Ruud's loss extended a brutal run of form in Melbourne for the Norwegian player. Jenson Brooksby's four-set win over Casper Ruud stole the headlines, and rightfully so, since the 22-year-old has only made it to the fourth round of a major once, while his opponent was a two-time Grand Slam finalist in 2022. Thursday was one of the biggest days in recent Grand Slam history for American men. Jabeur's exit has opened up the draw for Caroline Garcia or Aryna Sabalenka, who are the highest-seeded players left in that part of the draw. The other upset was by an American, with Katie Volynets taking out ninth-seeded Veronika Kudermetova. The Tunisian was one of two top-10 women's seeds to lose on Thursday. 2 seed Ons Jabeur crashed out of the tournament with a 1-6, 7-5, 1-6 loss to Marketa Vondrousova in the final match of the day. Upsets also dominated the headlines on the women's singles side. 4 seed Novak Djokovic came through his second-round match against Enzo Couacaud with relative ease, and Thursday's results cleared a stress-free path for him to reach the final. That should make for some great stories to emerge over the next few days in Melbourne. Only six of the 16 seeded players who were drawn in the bottom half of the men's singles draw are still in the tournament.

Taylor Fritz, the highest-seeded American in the tournament, was not immune to the upsets that riddled the men's singles draw on Thursday after he was defeated by Nikoloz Basilashvili. 23 seed Diego Schwartzman in straight sets, and Ben Shelton won an unseeded battle.

Tommy Paul took out 30th-seeded Alejandro Davidovich Fokina, J.J. Michael Mmoh earned the other high-profile upset by an American man as he hit back after losing the first set to No. Jenson Brooksby delivered the best result of them all when he took down No. Tennis players from the United States had a banner day at the 2023 Australian Open, with five American men producing victories on Thursday in Melbourne.
