Si Woo Kim has won 4 times on the PGA Tour – the biggest win of his career coming at The Players Championship in 2017, becoming the youngest ever winner at the age of 21. His last victory was in 2023 at the Sony Open in Hawaii.
He has also played in the Presidents Cup on three separate occasions, relishing the atmosphere and being one of the best performing International players.
He has underwhelmed somewhat at the majors – with a best finish of T8 at the 2025 PGA Championship – and so will be looking to push on in 2026 and better this record.
We know he’s a Callaway staffer, but what does have in play for the season?
A look inside Si Woo Kim’s bag
The South Korean made the switch in 2026 to the new Callaway Quantum range – but only for his driver.
He games a mini driver but is the Ai Smoke model.
Interestingly he opts for a Cobra 5 wood in amongst an all Callaway set up.
His 4-iron is a Callaway X Forged, whereas, the rest of his irons are Callaway Apex MB’s.
Kim uses three Callaway Opus wedges and an Odyssey putter.
His ball of choice is a Callaway Chrome Tour.
