Nadal won his 21st Grand Slam title at the Australian Open on Sunday, after coming back from two sets down to beat Daniil Medvedev.
The match lasted 5 hours, 24 minutes and was won by Nadal.
The Spanish southpaw had been in a three-way tie with Roger Federer and Novak Djokovic atop the all-time list for men's major winners but now stands alone thanks to his second career title at this hardcourt Grand Slam.
Nadal is the first man to win all four of the tennis majors at least twice. He won the Australian Open in 2009.
The second-seeded Medvedev was the favorite to win the Australian Open because of the absence of the top seed, Novak Djokovic, who was deported after an 11-day visa saga on the eve of the tournament because he failed to meet Australia's COVID-19 vaccine requirements.
He missed the tournament because of a knee injury.
He was trying to become the first man in the Open era to win a second Grand Slam title at the next major tournament. He lost in the Australian Open final.
