Erratic title contender Coco Gauff and three-time finalist Daniil Medvedev each moved into the second round at the Australian Open on Monday.

But the tournament is over for No. 7 seed Felix Auger-Aliassime, who retired from his opening match with cramps.

Gauff came through against Uzbekistan¡¯s Kamilla Rakhimova on center court 6-2, 6-3, but was less than convincing, with seven double faults and 31 unforced errors.

¡°I tried not to put too much pressure on myself,¡± she said. ¡°I am only satisfied if I win, but I am proud of myself regardless of how I get on.¡±

Her reward is a clash next with Venus Williams¡¯ conqueror Olga Danilovic.

Gauff last year beat world No. 1 Aryna Sabalenka at the French Open for her second Grand Slam crown, but her best performance on the Melbourne hardcourts was a semifinal run in 2024.

While she progressed, 2020 winner Sofia Kenin crashed out 6-3, 6-2 to fellow American Peyton Stearns as temperatures soared past 30 Celsius, and fans again faced long queues to get into Melbourne Park.

Canada¡¯s Auger-Aliassime was another casualty, calling for the trainer while down 3-6, 6-4, 6-4 to Portugal¡¯s Nuno Borges and pulling out.

¡°I want to be on the court competing with my opponent,¡± said Auger-Aliassime. ¡°I don¡¯t want to be just standing there, you know, like a punching bag.¡±

Russian Medvedev, the No. 11 seed on the men¡¯s side and runner-up in 2021, 2022 and 2024, warmed up for Melbourne with victory in Brisbane and ground to a 7-5, 6-2, 7-6 (7-2) win over Dutchman Jesper de Jong after twice being broken when serving for the match.

¡°The most important is to win,¡± he said.

Men¡¯s No. 13 seed Andrey Rublev also progressed, but women¡¯s No. 15 seed Emma Navarro tumbled out.
