On Sunday at TPC Sawgrass, 21-year-old South Korean Si Woo Kim cruised to a victory at The Players Championship with a flawless bogey-free round to earn $1.89 million.
Poulter is now inside the top-60 of the FedEx Cup rankings.
Last season, Kim was one of two PGA TOUR rookies to qualify for the FedExCup Playoffs finale at the TOUR Championship, thanks in part to a T15 showing at the Dell Technologies Championship - the second of four playoff events.
Two weeks ago, Poulter thought he had lost his PGA Tour card until officials realized a clerical oversight that restored his status and even gave him a spot in The Players Championship. Poulter not only got his card back, but the extra points put him in The Players Championship.
Kim, who said he had not decided when he will undertake his military service, delivered an impressive three-stroke victory in Ponte Vedra Beach, Florida. According to Kim, his win Sunday at The Players Championship won't keep the 21-year-old from serving his country at some point. In only six starts on the season, McIlroy is now No. 48 in the FedExCup standings. Rickie Fowler (2015), Tiger Woods (2013) and Matt Kuchar (2012) are the only Americans to win The Players Championship in the last 10 years.More news: Korean officials meet in attempt to repair ties

"I really wish I could have that benefit", Kim, who is only the second South Korean after K.J. Choi to reign supreme at Sawgrass, told reporters through a translator Sunday.
Stanley was nine shots lower than his playing partner, but a 75 still dropped him into a tie for fourth at 6-under with Rafael Cabrera Bello - who had one of the most sensational finishes in Players history when he made the first double-eagle at the par-5 16th hole, and added a birdie at No. 17.
Poulter stayed on Kim's heels throughout the final nine holes until a wayward approach shot into the trees right of the fairway on the closing hole ended his chance.

The smart money, if an worldwide player overtook American co-leaders J.B. Holmes and Kyle Stanley, was on veterans such as Poulter, Oosthuizen, Adam Scott (the previous youngest victor, at 23 in 2004) or Masters champion Sergio Garcia.
"If you are on your game and playing well, that's the things you do", said Oosthuizen.
"It just shows you how good a player he is and how cool and calm he is", Oosthuizen said. "And never once did he look flustered at all".
Ian Poulter salutes the crowd after nearly pitching his fourth shot into the hole on the 18th green.
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. But he had a stretch of six consecutive holes on the back nine without facing a par putt over two feet as he scrambled his way to the top.More news: Trump denies collusion with Russian Federation but says he 'speaks for himself'
