America’s Coco Gauff has been involved in a hilarious banter with Russia’s Andrey’s Rublev. Both players featured in an exhibition doubles contest just before the start of the Australian Open 2025.

Coco Gauff declared herself a fan of Joao Fonseca and acknowledged that she has been following the Brazilian's career since she first encountered him at the 2023 US Open.

Coco Gauff hilariously enacted Andrey Rublev's on-court grunt while training for the Australian Open 2025. The American is currently gearing up for the first Grand Slam of the year and was recently training for it alongside Andrey Rublev.

so Coco Gauff was calling out how fast she would try to hit some serves. Her guesses, and her deliveries, kept getting closer to 200 kph (125 mph) on Thursday evening, and when the 2023 U.S. Open champion and her partner, Andrey Rublev, had taken that game ...

Coco Gauff is the favorite to win the Australian Open and has been getting into the swing of things by adding a new element to her game - a grunt.

It seems Coco Gauff now has an extra weapon in her armoury as she bids to win the Australian Open for the first time. The American has started 2025 in stunning fashion, winning all five of her matches as Team USA claimed the United Cup, beating Poland in the final in Sydney.

At just 18, João Fonseca is putting the tennis world on notice, as illustrated by his clinical straight-sets victory over ninth seed Andrey Rublev at the Australian Open.

World No.6 Casper Ruud was knocked out in the men's singles second round after losing to Czech teenager Jakub Mensik. Meanwhile, German Alexander Zverev, American Coco Gauff stormed into the third round.
