The end was near and when Djokovic put away a smash on a first match point, he fell onto the court on his back. But well done guys, the atmosphere from all of them was wonderful, the support they gave to both Juan Martin and me.
"I was playing nearly at my limit all the time, looking for winners with my forehands, backhands, and I couldn't make them because Novak was there every time", Del Potro said.
After winning the first set 6-3, Djokovic was leading 3-2 in the second set (having broken Del Potro) and was serving to extend his lead to 4-2.
The Serb appeared to be on course for an easy victory when he went up a break in the second set to go up 6-3, 3-1.
Nonetheless, Djokovic, who thrives in such situations, showed his class yet again dismantling del Potro, who had been in fine form over the last two weeks in NY.
Djokovic though fought off the noise and Del Potro's challenging tennis to eventually take the second in the tiebreak.
With the quality of tennis only on the rise, the noise level inside the Arthur Ashe Stadium was deafening.
He picked up the pace with straight-sets victories over France's Richard Gasquet, Portugal's Joao Sousa, Millman and 2014 finalist Kei Nishikori to arrive at a title tilt with good friend Del Potro.
Devin Booker out indefinitely for Phoenix
The Suns went 3-7 in a three week stretch without Booker in December of previous year while going 2-10 the down the final stretch. Despite the injury, Booker played the next night against the Utah Jazz and made just three of 18 field-goal attempts.
The Serb has enjoyed a triumphant summer after his difficulties of the past two years when he endured a loss of confidence that accompanied a 54-week title drought followed by the low of elbow surgery in February.
The Serbian might be seeded 6th but he's making his 8th US Open final appearance, while Del Potro, seeded third, is only playing in a Grand Slam final for just the second time.
"Hard times but you learn from adversity", Djokovic said. "I just want to create from this moment onwards the most I can create for myself, to get the best out of myself in every possible moment".
Djokovic faced neither of his greatest rivals en route to the title in Flushing Meadows. "I will see you soon, on the court I hope". The most common utterance from chair umpire Alison Hughes aside from the score was undoubtedly, "Quiet please, players are ready", as she tried to stifle the rowdy spectators so del Potro and Djokovic could serve. After the four wrist surgeries that derailed his career between 2011 and 2015, Del Potro is back to his terrifying best.
"Today I really am".
But in the last eight weeks the 31-year-old has resembled the Grand Slam machine that held all four major titles at the same time in 2016, wining three of his last four events including Wimbledon and U.S. Open.
Although he was riding high coming into the Open, Djokovic was among the many struggling with crushing heat and humidity in the first week.
