Early Life and Golf Journey
Si Woo Kim was born on June 28, 1995, in Seoul, South Korea. His introduction to golf came entirely through his father, Kim Doo-young, who remains the only coach Si Woo Kim has ever credited.
That family-first approach to development shaped the disciplined ball-striker that Tour fans know today.
Kim attended Sinsung High School in Anyang City, Gyeonggi Province, before going on to study at Yonsei University in Seoul.
His mother supported his progression by helping facilitate a move to Thailand so he could train in better conditions — a sacrifice that clearly paid off.
He turned professional in 2012 and immediately made history. At just 17 years and five months old, Kim graduated from the PGA Tour Qualifying School in 2012 — the youngest player ever to do so.
PGA Tour rules prohibited membership until age 18, so he spent part of 2013 on the Web.com Tour, making four cuts in seven starts.
After a difficult maiden PGA Tour season in 2013, Kim lost his card but regained it through the Web.com Tour.
He earned his first professional win at the 2015 Stonebrae Classic on the Korn Ferry Tour (then Web.com Tour), beating Jamie Lovemark and Wes Roach in a playoff. That Korn Ferry victory set the stage for everything that followed on the PGA Tour.
Professional Golf Career
Kim’s PGA Tour career began in earnest during the 2015-16 season, and he wasted no time making an impact.
His first PGA Tour win came at the 2016 Wyndham Championship, where he finished five shots clear of the field at 21-under par. He was the youngest winner on Tour that season.
What followed in 2017 cemented his name in golf history. Kim won The Players Championship at TPC Sawgrass by three shots at 10-under, becoming the youngest winner in the event’s history at 21 years old.
It remains one of the most stunning upsets in the tournament’s modern era — he ranked just 73rd in the world when he lifted the Waterford crystal trophy, the second-lowest ranking among Players champions in history.
After a quieter stretch, Kim won again at the 2021 American Express, overpowering Patrick Cantlay by one stroke with a closing 64 at a score of 23-under par.
He captured his fourth PGA Tour title at the 2023 Sony Open in Hawaii, making birdies on the final two holes to beat Hayden Buckley by one shot at 18-under.
Beyond wins, Kim has been a consistent major championship presence. His best finish is a T12 at the 2021 Masters and a T8 at the 2025 PGA Championship at Quail Hollow.
He also holds a remarkable record in major championship holes-in-one — his 238-yard ace at the 2024 Open Championship at Royal Troon and his 252-yard ace at the 2025 PGA Championship are the two longest aces ever recorded in men’s major championship history, according to Golf Monthly.
Kim has represented the International team at three Presidents Cups (2017, 2022, 2024), accumulating six points from eleven matches.
He helped South Korea claim gold at the Asian Games, earning an exemption from mandatory military service. He also represented South Korea at the 2020 Tokyo Olympics, finishing 32nd.
In the 2026 season, Kim has posted nine top-10 finishes — his best top-10 total since his record-breaking 2023 campaign — and climbed to a career-best OWGR of 20th in May 2026.
Caddie
Si Woo Kim’s current caddie is Manuel “Manny” Villegas, younger brother of PGA Tour professional Camilo Villegas.
The partnership began in 2022 ahead of that year’s Presidents Cup and produced immediate results: Kim won the 2023 Sony Open in Hawaii with Villegas on the bag just months after they started working together.
Kim publicly credited Villegas for the club selection that led to his iconic 238-yard hole-in-one at the 2024 Open Championship at Royal Troon, saying his caddie told him to “hit hard with a 3-iron.”
Before Villegas, Brian Vranesh caddied for Kim during his 2021 American Express victory.
Wife
Si Woo Kim married Oh Ji-hyun on December 18, 2022, in a small ceremony with family and friends. Ji-hyun is a professional golfer who won seven times on the Korean LPGA Tour (KLPGA), with her last KLPGA victory coming at the 2021 Jeju Samdasoo Masters.
The couple first met at a golf event in 2014 and began dating in 2021.
Since marrying, Ji-hyun has stepped back from active competition to support Kim’s PGA Tour career and focus on their family.
The couple welcomed their first son, Theo, in February 2024. In a 2025 interview, Kim described fatherhood as transformative, noting that family had become a central part of his purpose alongside golf.
Ji-hyun famously caddied for Kim during the 2023 Masters Par 3 Contest in a widely shared moment that resonated with golf fans worldwide.
Si Woo Kim’s Net Worth Details
As of 2026, Si Woo Kim’s has an estimated net worth of $29 million.
He built this fortune through consistent PGA Tour prize money exceeding $35.7 million in career earnings, long-running equipment and apparel endorsements, and a growing portfolio of brand partnerships that extend his income well beyond the fairway.
Career Prize Money
Si Woo Kim’s career prize money on the PGA Tour surpassed $35.7 million as of mid-2026, making him the all-time Korean earnings leader on Tour — surpassing both Im Sung-jae and veteran K.J. Choi, as reported by the Seoul Economic Daily in May 2026.
For context, the all-time PGA Tour prize money leader is Tiger Woods at over $120 million.
His single-season best on the PGA Tour was 2023, when he earned $5,397,030 — fueled by his Sony Open victory ($1,422,000 in winner’s prize) and a string of high finishes throughout the year.
His 2025 season yielded approximately $4 million, with a career-high 14 top-25 finishes.
In 2026, Kim has been one of the hottest players on Tour, posting a T2 at the Farmers Insurance Open ($726,400) and a T3 at the WM Phoenix Open ($439,680), among multiple other high finishes.
Kim’s highest single-tournament payout came from his 2017 Players Championship win, worth approximately $1.89 million at the time.
The Players has since grown significantly in prize fund, meaning that same win today would be worth considerably more. Across his full PGA Tour career, he has averaged over $2.3 million in prize money per season, a rate that underlines elite consistency.

Endorsements
Equipment is the foundation of Kim’s endorsement income.
He signed with Callaway Golf in 2018, following his 2017 Players Championship win, in a full-staff deal covering woods, irons, wedges, golf ball, and Odyssey putter.
As Golf Digest reported at signing, Callaway’s senior VP of global sports marketing described Kim as “a complete player” with the “talent and mindset” to succeed long-term on Tour. That deal has remained in place, with Kim using prototype Callaway irons and the Callaway Quantum Triple Diamond driver heading into the 2026 season.
On the apparel front, Kim made a notable switch at the start of 2026. He signed with Primo, a golf clothing brand owned by popular golf content creator Grant Horvat, pairing the apparel with Nike golf footwear.
The partnership gave Primo its highest-profile Tour ambassador and gave Kim a fresh, modern identity off-course.
In April 2025, Kim expanded his sponsor portfolio by announcing a partnership with Yeet Casino, sharing the news directly with fans via Instagram.
While outside the traditional golf-brand ecosystem, the deal reflects Kim’s growing commercial appeal and willingness to work with brands outside conventional golf sponsorship circles.
