Here's another way to think about it all: When Sampras beat Andre Agassi in the 2002 U.S. Open final, in what would turn out to be Pistol Pete's last professional match, it not only established a new record for men's Slam trophies at 14, it also was two more than anyone else in history had managed to collect.
A focused Djokovic continued to apply pressure in the third set until Del Potro finally cracked on serve to fall behind 5-3, with the Serb closing out the match with a ferocious overhead victor. But when Djokovic faced three break points in the following game, an epic that required 22 points to settle, he saved them all. One game alone in the second set lasted 20 minutes.
The third and final set almost followed the same script, as Djokovic again broke del Potro to take a 3-1 lead only for the Argentinian to break back and level the set at 3-3. This follows a two-year Slam drought for the 31-year-old Serb, who suddenly is tied with Pete Sampras for the third-most major trophies by a man, trailing only Roger Federer's 20 and Rafael Nadal's 17.
This time Djokovic is No.3 behind Nadal and Federer, but the stunning three-year first will have tennis fans asking if it really is 2018.
Del Potro was the sentimental favourite as he attempted to win a second slam title nine years after his first, having suffered two serious wrist injuries, the second of which he feared would end his career.
Djokovic, who won Wimbledon in July, will climb to third in the world after back-to-back Grand Slam victories.
'I don't know the answer.
"When I had the surgery on my elbow I could truly understand what Juan Martin was going through".
"I love Serena, first of all", Djokovic said.
On the other hand, Del Potro was relying heavily on his serves and power.
Djokovic had tumbled down the rankings, slowed previous year by an elbow injury and a loss of confidence that accompanied a 54-week title drought. Her grandfather, who lives in Nemuro, Hokkaido, expressed his joy, saying, "I want her to make a spectacular showing at the 2020 Tokyo Olympics, too".
Djokovic declared Ramos "shouldn't have pushed Serena to the limit" when asked about Williams in his press conference.
It made for a partisan atmosphere in the biggest tennis stadium in the world and, with the roof closed because of rain, led to a cauldron of noise.
Leading 4-3, Djokovic caught Del Potro off guard with his exceptional patience and strong strokes to break Del Potro's serve.
In the tiebreak, Del Potro looked susceptible to forehand errors and Djokovic showed huge courage and quality to take it away from Del Potro, going up 2-0 in the final.
When it ended, thanks to a three-game closing run by Djokovic, he flung his racket away and landed on his back, arms and legs spread wide. "But I'm happy for Novak and his team".
"I was playing at my limit nearly all the time, looking for winners", he said.
