Choi even gave the youngster some advice before the round. "That's why I could do well".
SERGIO GARCIA is not only a victor in golf but also in love.
The Spaniard's second shot on the par-five 16th took a kick off the front of the green before heading straight for the cup marking the first time a double eagle has been recorded at the 525-yard hole in tournament history. "I'm very honored to be the champion for this incredible fifth major event".
"Usually I'm very nervous but last year I won one and I got a two-year extension", Kim said. Adding, "I'm looking forward to working hard from now on".
"I still can't believe that I'm the champion and I'm the youngest champion for this championship and I'm very honored to be the champion for this awesome fifth Major event and I'm looking forward to working hard from now on", said Kim, whose other PGA Tour victory was at last year's Wyndham Championship.
PRESIDENTS CUP: Along with all the perks for winning - starting with a five-year exemption on the PGA Tour - Si Woo Kim thought about becoming the next South Korean player in the Presidents Cup later this summer.
Kim's countryman, 30-year-old San Moon Bae, a three-time United States tour victor, is now completing his military service after losing a court case to defer it.
Just over four years ago, Kim came over to America to play the final version of PGA Tour's qualifying school.
Compatriot Sang Moon Bae - also a two-time victor on the PGA Tour - is now serving two years of mandatory military service.
From thinking he had lost his PGA Tour playing card to finishing in a tie for second at The Players Championship in the space of a few weeks, Ian Poulter has conceded that one's fortunes in golf can change at the drop of a hat.
Then Kim parred his way through the back nine, his last putts no longer than four feet on any hole as he calmly ignored winds and tension to prevail.
Poulter shanked his second shot from the right rough on the 18th, and it bounced off hospitality tents, down a cart path and into a palmetto bush.
Poulter admitted afterwards that he was keen to play a number of European Tour events this summer, and he will join the likes of Rory McIlroy, Henrik Stenson and Justin Rose in a star-studded field for the first of seven Rolex Series tournaments.
"It was a big shock to the system to hit one of those nasty shanks when I've hit it as good as I have all week", Poulter said.
A closing 1-under 71 left Poulter tied with Louis Oosthuizen tied for second at 7-under, a $924,000 payday.
Cabrera Bello became the first player to fire an albatross at the par five 16th, while a birdie at 17th helped the 32-year-old to card a final round 70.
3 - It was a bad day for 54-hole co-leader Kyle Stanley who closed with a 75 to finish in a tie for fourth.
Third-round co-leader J.B. Holmes ballooned to an 84 on Sunday and plummeted into a tie for 41st at 291.
