Si Woo Kim

Si Woo Kim is a South Korean professional who made history before he was old enough to join the PGA Tour. At 17 he became the youngest player ever to graduate from Tour qualifying school, though rules kept him from taking up membership until his 18th birthday. After a tough first stint, he rebuilt on the Web.com Tour and won the 2015 Stonebrae Classic to earn a full card.

His first PGA Tour title came at the 2016 Wyndham Championship, and the following spring he won The Players Championship at 21, closing with a bogey-free 69 to become the youngest winner in the event's history. He has added The American Express in 2021, with a closing 64, and the 2023 Sony Open, where he birdied the last two holes. Kim has also been a regular on the International side at the Presidents Cup. He finished runner-up to Wyndham Clark at the 2026 CJ Cup Byron Nelson.
