An emotional Novak Djokovic completed an extraordinary turnaround from the events of a year ago when he resumed his hegemony over the Australian Open. By doing so he equalled Rafael Nadal’s tally of 22 Grand Slam trophies in what was his 33rd final, one in which the crushing weight of experience was brought to bear. That included the third set tiebreak, in which he raced to a 5-0 lead and then remained calm when Tsitsipas took the next three points. It was then that it became obvious who owns 21 Grand Slam titles compared to zero. Tsitsipas dug in well to take it to a tiebreak, but again did not have the composure to match his opponent.
