Top surviving seed Raonic enters quarters

The Canadian, the highest surviving seed after the early departures of Andy Murray and Novak Djokovic, stamped his authority on a sometimes tempestuous match by breaking the Spanish world number 13 to win the third set. 

Teak tough Bautista Agut is nothing if not a fighter but Raonic, who said he had been suffering from a fever after his third-round match, raced away with the fourth set to seal the victory with a forehand winner down the line. The 26-year-old, who fired down 33 aces and 75 winners in the two hour, 52-minute contest, will next meet Rafael Nadal or Gael Monfils as he continues his quest for a maiden Grand Slam title.

Grigor Dimitrov reached his first Slam quarter-final in over two years by defeating an injury-hampered Denis Istomin 2-6 7-6(2) 6-2 6-1 to end the Uzbek wildcard’s fairytale run at Melbourne Park. Istomin, who sensationally knocked Novak Djokovic, laboured with an apparent left thigh injury after winning the first set and Dimitrov took full advantage of his opponent’s struggles.
