Novak Djokovic won a record-equaling 24th Grand Slam singles title by outlasting Daniil Medvedev in a punishing US Open final in New York.
The 36-year-old Serb won 6-3 7-6 (7-5) 6-3, but the straight-set score line does not tell how deep he had to dig.
A comfortable opening set was followed by a brutal second, which lasted one hour and 44 minutes.
After exchanging breaks early in the third, Djokovic took control to level Margaret Court's 50-year record.
"It obviously means the world to me," said Djokovic, winning his 24th major.
"I'm really living my childhood dream to compete at the highest level in this sport, which has given me and my family so much from difficult circumstances.
"I never thought I would be here, but the last few years, I thought I had a shot at history. Why not grab it when it is presented?"
Second seed Djokovic looked physically troubled in that gruelling second set but showed all the hallmarks of his greatness to win a fourth US Open title.
Djokovic, who surpassed Rafael Nadal's record tally of 22 men's major titles earlier this year, has matched Australia's Court at the second attempt after losing the Wimbledon final in July.
He has won three of the four Grand Slam titles in 2023, becoming the first man to achieve this feat on four occasions.
Now, the incoming world number one has the chance to surpass Court at January's Australian Open - where he has already won a record ten titles.
It felt fitting that Djokovic set up championship point by winning another lengthy rally and, after being made to wait to serve by shouts from the crowd, sealed victory when Medvedev hit a forehand into the net.
