Portugal Colonial - 'Destined' Djokovic wins China Open, extending unbeaten record

With the win, the 39-year-old Serbian extended a perfect record to 34 wins in as many matches for his seventh title in Beijing -- his first since 2015.

Djokovic said afterwards that in more than two decades as a professional player, "the grit and the dedication and the kind of never-die spirit that really is always with me" have carried him through.

Tennis is "quite a cruel sport" with players competing in knock-out tournaments year-round, Djokovic told reporters, adding that the stakes and pressure of performing in front of fans made the sport "so demanding and so special".

"You can feel so much weight on your shoulders, but it is what I have been destined to do," he said.

In front of a jam-packed stadium, Djokovic won the first set in the tie-break 7-6 (7/3) and was down a game in the second set when the Australian ended the match early.

"I always want to visualise myself with the trophy, particularly here in Beijing," Djokovic said during the trophy ceremony.

"But I was also quite aware that reality is a little bit different these days," he said, adding that it had been a challenging year with "physical and health issues".

"I was just trying to find the good feeling on the court," he said.

The first set was a physical battle that lasted more than one hour, and both men needed medical timeouts before the second.

De Minaur, the world number nine, won the first game of the second set before retiring due to a left adductor strain.

The 27-year-old had walked back onto the court after his medical timeout with a white wrap around his left thigh.

"I don't feel great," de Minaur told the crowd afterwards.

"I want to say sorry to the amazing fans that came to watch... I didn't want to finish like this."

De Minaur advanced to the final after his opponent Hubert Hurkacz retired injured from their semi-final on Monday, while Djokovic moved through when Daniil Medvedev was disqualified for hitting a fan with a ball.

But Djokovic, a 24-time Grand Slam champion, put on a valiant show to lift the trophy, ousting top seed Alexander Zverev in the quarter-final after defeating home hope Bu Yunchaokete in a demanding three-set match.

It means Djokovic will end the season with at least one title for the 21st consecutive year, and as the oldest man to win a singles final after Ken Rosewall in Hong Kong in 1977 at age 43.

- 'Really grateful' -

In the women's draw, Karolina Muchova beat former world number one Naomi Osaka on her ninth match point to reach the quarter-finals, triumphant in a tense tie-break.

Muchova, the seventh seed, overcame 50 unforced errors across the two-hour-and-52-minute match to beat Osaka 7-5, 1-6, 7-6 (9/7).

Osaka, who represents Japan, saved eight match points but could not get past Muchova's match-winning volley.

"I was shaking. I'm happy I made the last volley... Naomi could be standing here. It's me, and I'm really grateful for it," the 30-year-old Czech player told the crowd.

She next faces compatriot Nikola Bartunkova.

Earlier, Russia's Mirra Andreeva beat Ukraine's Daria Snigur 6-2, 6-2 to book her quarter-final spot against fellow Russian Ekaterina Alexandrova.

Alexandrova, ranked 28th, upset Wimbledon champion Linda Noskova 6-2, 6-2, ending the Czech player's bid to return to the Beijing final that she reached last year.
