Muller

Alexandre Muller defeated Alexei Popyrin in a grueling five-set first-round match at the Australian Open on January 19, 2026, ending the Australian's hopes in his home Grand Slam. Popyrin, who led at key moments, succumbed to a calf injury flare-up and unforced errors despite serving 40 aces. The Frenchman advanced to face Alexander Zverev next.
