And the 21-year-old is also comfortably the youngest victor of the Players Championship, surpassing the record set by former world No 1 Adam Scott, who was 23 when he wonat Sawgrass in 2004.
Kim was almost flawless Sunday on the TPC Sawgrass, closing with a 3-under 69 with no bogeys on his card for a three-shot victory in golf's biggest tournament this side of the major championships.
Kim also thanked compatriot Choi for helping him close out the victory.

But even though form was not on his side, there have always been signs that Kim is destined for...
He made an immediate impact upon his return to the Tour past year, however, winning his maiden PGA Tour title at the Wyndham Championship.
"I've enjoyed it and hopefully this is just a stepping stone to pressing on for the rest of this year".
Through the first nine holes on Sunday, Kim was 3-under par. Speaking after his maiden tour victory, the 21-year-old has resigned himself to serving his country.
"I'm very excited to play at the Presidents Cup", Kim said.
"I haven't decided when, but I have five years of exemption, so we will see".
Although the Players Championship is not a major, it has one of the biggest prize pots on the PGA tour, bagging Kim 1.9 million dollars and a host of exemptions to qualify for other competitions, including the Masters. Ian Poulter pulled within a stroke of the champion, but he too fall apart on the back nine. Now, he's nearly assured of being in the season-ending FedEx Cup play-offs.
"I was a little nervous before I played the final round", Kim said.
"It's been a tough 18 months".

However, even though he failed to earn his first tournament victory since 2012, there was still plenty of positives for the Englishman to take away.
He became the third global Players champion in four years and led seven worldwide players among the top-10. "My putting was really solid, bit shaky on the front nine today but then I putted well on the back nine".
"I know he hit a couple of incredible shots yesterday to get himself out of trouble, driver off the deck on 14 was a pretty impressive shot".
World No.3 Jason Day had a Sunday afternoon to forget.
He played last four holes in just eight shots, starting with the first albatross in TPC Sawgrass history when his 8-iron on the par-5 16th hole caromed off the bank of a bunker and ran into the pin before dropping for a 2.
