Fans appear to boo Andy Murray at Australian Open
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.
