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 T12 at the 2021 Masters – and so will be looking to push on in 2025 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. He has in the play the driver and fairway woods.
He also games a mini driver but is the Ai Smoke model he goes for and not the 2025 Elyte.
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 O Works Black 3T Putter.
His ball of choice is a Callaway Chrome Soft X.
