Follow live updates from the Australian Open as the fourth round comes to a close at Melbourne Park. Daniil Medvedev has advanced to the quarter-finals after seeing off Maxime Cressy 6-2 7-6(4) 6-7(4) 7-5 in a tense match. The US Open champion was left flustered by Cressy’s serve and volley style in a dramatic third set but eventually converted a break point late on in the fourth to set up a meeting with Felix Auger-Aliassime, who outlasted veteran Marin Cilic 2-6 7-6(7) 6-2 7-6(4). There was a significant upset earlier in the day as Alize Cornet defeat former world No 1 Simona Halep 6-4 3-6 6-4 to reach her first grand slam quarter-final at the 63rd attempt.
There were two further epic matches on a marathon day of tennis, as the men’s number four seed Stefanos Tsitsipas battled past the in-form Taylor Fritz 4-6, 6-4, 4-6, 6-3, 6-4 in five sets. Tsitsipas secured a late break of serve to finally edge ahead of Fritz, who led throughout the match, and claim a place in the quarter-finals, where he will face Jannik Sinner. The drama was not done there as, in another late match at Melbourne Park, the 36-year-old Kaia Kanepi advanced to the quarter-finals of the Australian Open for the first time as she ousted the women’s number two seed Aryna Sabalenka.
