2022 Australian Open – Men's singles
Rafael Nadal defeated Daniil Medvedev in the final, 2–6, 6–7, 6–4, 6–4, 7–5 to win the men's singles tennis title at the 2022 Australian Open. It was his second Australian Open title and 21st major singles title overall, surpassing the all-time record he had jointly held with Roger Federer and Novak Djokovic. Nadal became the fourth man, after Roy Emerson, Rod Laver, and Djokovic, to achieve the double career Grand Slam, and the second in the Open Era. He also became the first man in the Open Era to win the Australian Open final after losing the first two sets. This marked the third consecutive year a man trailed by two sets in a major final yet rallied to win, following Djokovic's two-set comeback at the 2021 French Open and Dominic Thiem's at the 2020 US Open. Nadal became the seventh man in the Open Era to come back from two sets down in a major final to win the title.
Djokovic was the three-time reigning champion, but did not compete after [|his visa was cancelled] shortly before the tournament began due to an intervention from Australia's Immigration Minister Alex Hawke, citing risks to public health and good order in Australia. That meant Nadal was the only former champion to compete in the tournament, with both Federer and Stan Wawrinka sidelined by injury. Djokovic retained the world No. 1 singles ranking despite being unable to defend his points after Medvedev and Alexander Zverev lost in the final and fourth round, respectively.
Matteo Berrettini became the first man born in the 1990s to reach the quarterfinals at all four majors, and the first Italian man to reach the semifinals of the Australian Open.
This also marked Feliciano López’s 79th consecutive grand slam appearance, an Open Era record previously held by Roger Federer. López streak started at the 2002 French Open and concluded 20 years later in Melbourne.
Seeded players
The following are the seeded players. Seedings are based on ATP rankings as of 10 January 2022. Rank and points before are as of 17 January 2022.As a result of pandemic-related adjustments to the ranking system and changes to the ATP Tour calendar in 2020 and 2021, ranking points after the tournament were calculated as follows:
- Players who were defending points from the 2020 tournament had their 2020 points replaced by points from the 2022 tournament; as of 31 January 2022, these players could also count their 2021 points towards their ranking if the 2021 points exceeded their 19th best result
- Players who were defending points from the 2021 tournament had their 19th best result replaced by their points from the 2022 tournament; these players continued to count their 2021 points alongside their 2022 points at the end of the tournament because the 2021 tournament was delayed by three weeks compared to the normal schedule and the "better of" logic for calculating ATP ranking points had been discontinued
- All players who have points from the 2021 tournament still counting towards their ranking on 31 January 2022 will have those points dropped on 21 February 2022 and replaced by their next best result
