Third seed Stefanos Tsitsipas extended his winning streak this year with another ruthless victory at the Australian Open on Friday then played down his chances of a first Grand Slam crown. 

The 24-year-old is yet to drop a set in Melbourne and clinched his seventh straight win of 2023 by beating Dutchman Tallon Griekspoor 6-2, 7-6 (7/5), 6-3 on Rod Laver Arena. With defending champion Rafael Nadal and World No.3 Casper Ruud both out, Greece’s Tsitsipas is the highest seed left on the men’s side. He set up a Last 16 clash with the dangerous Jannik Sinner after the Italian 15th seed stormed back to crush Hungary’s Marton Fucsovics 4-6, 4-6, 6-1, 6-2, 6-0. It will be a rematch of their Melbourne Park quarter-final last year, which Tsitsipas won in straight sets, before exiting in the Last 4.
