Nick Kyrgios and Thanasi Kokkinakis's bid to repeat their Australian Open doubles triumph of 2022 ended in retirement in on Thursday when the latter was unable to continue their first-round tie.

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

Kokkinakis was hampered by a long-standing pectoral injury as he went down 7-6 (7-3) 3-6 6-3 5-7 3-6 to Jack Draper in a four-hour-and-35-minute heartbreaker. Speaking after the match, Kokkinakis said he wouldn't even be able to lift his right arm to serve on Thursday night.

Thanasi Kokkinakis says he suffered pectoral muscle injury "torture" in marathon Australian Open second-round defeat to England's Jack Draper.

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 said the abuse he received during his thrilling five-set Australian Open comeback over home favourite Thanasi Kokkinakis inspired him to raise his level as the British No 1 reached the third round of the grand slam for the first time.

Jack Draper conjured the spirit of Andy Murray to claw his way back from the brink of defeat against home favourite Thanasi Kokkinakis at the Australian Open. Two years ago, Murray famously recovered from two sets and a break down against Kokkinakis to win a second-round match that finished at 4.05am.
