Novak Djokovic was looking weary and worn down. He trailed Dominic Thiem in the Australian Open final, miscues mounting, deficit growing.
Djokovic did what he does, though. He refused to lose, waited for a chance to pounce and found his best tennis when absolutely necessary.
Regaining his stamina and strokes, Djokovic came back to edge Thiem 6-4, 4-6, 2-6, 6-3, 6-4 Sunday night for an eighth Australian Open title, second in a row, and 17th Grand Slam trophy overall.
Only Roger Federer, with 20, and Rafael Nadal, with 19, have won more men's Grand Slam singles trophies.
A little more than six months after saving a pair of championship points against Federer en route to winning a five-set Wimbledon final, Djokovic again showed that he can't ever be counted out.
This victory improved Djokovic's combined record in semifinals and finals at Melbourne Park to 16-0 and means he will return to No. 1 in the rankings, replacing Nadal in that spot.
No other man in the history of tennis has won this hard-court tournament more than six times.
It did not come easily this time for Djokovic, a 32-year-old from Serbia. He lost six games in a row in one stretch to Thiem, who plays a similar game and eliminated Nadal in the quarterfinals.
Djokovic adds to his collection, the silver Australian Open trophy he already had won in 2008, 2011-13, 2015-16 and 2019.
He adds that haul to his five titles from Wimbledon, three from the U.S. Open and one from the French Open.
Thiem, an Austrian who is 26, was appearing in his third major final. He has lost them all, including to Nadal at Roland Garros each of the past two years.
Thiem was trying to become the first man born in the 1990s to win a Grand Slam singles title and was hoping to end the recent run of dominance by the sport's Big Three of Djokovic, Nadal and Federer.
Instead, the Big Three have won 15 of the past 17 Australian Opens, 13 consecutive majors overall and 56 of the last 67.
In addition, Djokovic himself is now the first man in the professional era to win a Slam title in each of three decades -- the 2000s, 2010s and, now, 2020s. The only other man in the sport's century-plus history to do it was Ken Rosewall, with major championships in the 1950s, 1960s and 1970s.
Djokovic keeps gaining on rivals Federer and Nadal: This was his fifth trophy from the past seven Slams, going 5-0 in finals in that span.
