A seething Thanasi Kokkinakis has described his ongoing pectoral muscle issues as “physical and mental torture” after losing a five-set epic at the Australian Open.

Thanasi Kokkinakis was warned for "bending the rules" as he called the physio during his marathon battle with Jack Draper in Melbourne.

Australian tennis star Thanasi Kokkinakis has stunned his opponent with an amazing act of sportsmanship at a critical moment of their second-round Australian Open clash. British No.15 seed Jack Draper was serving at two sets to one down, and trailing by a break in the fourth when he was about to be denied a certain point after a long rally.

Jack Draper admitted his critics were right to question his staying power but was proud to have put those doubts to bed with a third-consecutive five-set win at the Australian Open.

Former junior rivals Jack Draper and Jacob Fearnley fought their way into the third round of the Australian Open despite being on the wrong end of two of the rowdiest crowds you will find on the professional tour.
