Wheelchair maestro Dylan Alcott has been left choked with emotion after becoming the first man in any form of tennis to earn the calendar year 'golden slam' of all four major titles and Paralympic or Olympic gold at the US Open.
The 30-year-old Melburnian looked close to tears as he admitted after his emphatic 7-5 6-2 triumph over Dutch teenager Niels Vink in the quad singles final on Sunday that this could have been his farewell to Flushing Meadows.
And if it is the last time the New York slam sees this remarkable Australian entertainer, Alcott was happy to leave them with a typically effervescent farewell.
"Thanks for making the dreams of a young fat disabled kid with a really bad haircut come true because I cant believe I just did it!" he told the Louis Armstrong Stadium crowd.
"I just cant believe I just won the golden slam!"
Then he was off to the Arthur Ashe stadium to watch the men's singles final between Daniil Medvedev and Novak Djokovic, opening a can of beer for the cameras, pouring it into his trophy, glugging it all down and then plonking the upside-down Cup on his head.
Cue cheers all round from the Flushing Meadow crowds who had earlier watched him produce a vintage display to outclass the 18-year-old Vink, the sport's new rising star who had pushed him to three sets in a classic at the Paralympics.
This time, the only real worry seemed to come at the start for Alcott as he waited a mite anxiously for his match wheelchair to be brought to the court.
At the end of an uneven first set in which serve was broken seven times, Alcott produced his best tennis, racing to retrieve a net cord and then somehow finding a dazzling lob to win the set 7-5 with his 17th winner of the stanza.
From there, he was in complete control, taking victory in an hour and a quarter after adding another 11 winners.
After praising Vink for pushing him to a new level, Alcott told the crowd: "I used to hate myself so much, I hated my disability, I didnt even want to be here any more and then I found tennis and it changed and saved my life.
"And now I'm the only male in any form of tennis to win the golden slam, which is pretty cool."
He's now won 20 of his 21 matches this season and a 15th singles grand slam but is considering his future after achieving something unsurpassable.
"I've got to be up front - I don't know if I'll be back here," he told the crowd.
Earlier, Dutchwoman Diede de Groot, the top seed, had achieved the same 'golden slam' in the women's wheelchair singles, beating Japan's Yui Kamiji 6-3 6-2 in a repeat of the gold medal match at the Tokyo Paralympics.
The equivalent men's singles saw Japan's top seed Shingo Kunieda beat Briton Alfie Hewett 6-1 6-4.
