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.
After going the distance against both Mariano Navone and Thanasi Kokkinakis, Draper again came from two sets to one down to see off unseeded Australian Aleksandar Vukic and set up a fourth-round clash with Carlos Alcaraz.
