#4: The longest men's singles final in the Open Era

In an epic 2012 Australian Open final, Novak Djokovic overcame Rafael Nadal 5-7, 6-4, 6-2, 6-7(5), 7-5 to successfully defend his title.
At 5 hours 53 minutes, it became the longest men's singles final in the Open Era, and the longest final on the ATP Tour, surpassing the estwhile record of 5 hour 14 minute mark set by the 2005 Rome Masters final where Nadal beat Guillermo Coria.
#5: No player in the Open Era has won the Australian Open from two sets or match points down in the final

Rod Laver saved a match point against compatriot Neal Fraser to win the 1960 Australian Open. It remains the third and latest instance of an Australian Open winner saving championship points in the final, the other two instances being 1927 (Gerald Patterson beat John Hawkes) and 1947 (Dinny Pails beat John Bromwich).
Since tennis went professional in the summer of 1968, only two Grand Slam champions have saved championship points in the final.
Novak Djokovic's victory over Roger Federer after saving match points in the 2019 Wimbledon final is the first such instance. The only other such instance happened at 2004 Roland Garros where Gaston Gaudio saved two match points against compatriot Guillermo Coria.
No Australian Open champion has successfully overturned a two-set deficit in the final since Roy Emerson beat Fred Stolle 7-9, 2-6, 6-4, 7-5, 6-1 in the 1965 title match.
