Early Career

He spent 2013–2015 grinding on the Web.com Tour, winning the 2015 Stonebrae Classic in a playoff becoming the second-youngest winner in that tour’s history behind Jason Day. That performance earned his PGA Tour card for 2016.
Professional Career
Kim’s PGA Tour breakthrough came at the 2016 Wyndham Championship, making him that season’s youngest winner. A year later, at just 21, he stunned the golf world by winning The Players Championship, becoming its youngest-ever champion.
He added The American Express in 2021 and the Sony Open in Hawaii in 2023. Kim has also represented the International team at multiple Presidents Cups and won Asian Games gold with South Korea’s team in 2022.
His 2026 season has been especially strong, with a runner-up finish at the CJ Cup Byron Nelson and a career-best major finish, T6, at The Open Championship
