He was the first new Australian Open men's singles champion since Stan Wawrinka in 2014. Medvedev lost the final after winning the first two sets, making him the only player in the Open Era to lose two major finals after having a two-set lead and the second to lose all of his first three Australian Open finals, after Andy Murray. Medvedev also set Open Era records for the most time spent playing at one edition of a singles major, at 24 hours and 17 minutes, and for the most sets played in a singles major, at 31.
