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.
