The Hype Turned Into Reality
Skepticism was widespread when the Presidents Cup rosters were revealed at the start of this month concerning the tour’s hottest young player, Jackson Koivun. He proved the hype justified by winning his first pro event at the 3M Open soon after finishing his collegiate season at Auburn University. The US squad and Captain Brandt Snedeker gained greatly from a bold choice to include him on the Presidents Cup roster. A decisive win against International star Si Woo Kim in Sunday singles contributed to his 2–0–1 record for the event. Koivun’s play guarantees that his inclusion will not be debated again for the foreseeable future.
Inside the Bag That Delivered
According to GolfWRX reporting, Koivun’s equipment choices reflect a player who understands the nuances of ball flight and spin control. His driver setup features a Titleist GT2 adjusted to 8 degrees, paired with a Fujikura Speeder 661 TR X shaft. This combination suggests a desire for a lower, more penetrating ball flight that holds up in various wind conditions. Moving to his fairway woods, he relies on a Titleist GTS3 Prototype set to 15 degrees, loaded with a Graphite Design Tour AD DI 8 X shaft. This specific prototype model indicates he is testing new technologies to maximize distance while maintaining accuracy off the deck.
The iron setup is where Koivun’s game shows its most interesting blend of game improvement and traditional blade feel. GolfWRX notes he carries a Titleist T250 in the 3-iron, followed by a Titleist T100 in the 4-iron. From the 5-iron through the 9-iron, he switches to Titleist 620 MB Prototype clubs. This mixed set allows him to hit higher, easier shots from the long irons while having the workability of a muscle back for the scoring clubs. While the 3-iron uses a Graphite Design Tour AD DI HY 95 X, shafts from the 4-iron to the pitching wedge are Project X 6.5.
His wedge progression is tailored for precise distance gaps. He uses Titleist Vokey Design SM11 wedges in 46-10F, 50-08F, 54-08M (bent to 55 degrees), and 60-04T. The shafts vary slightly here, with Project X 6.5 in the 46 and 50-degree wedges, Project X 6.0 in the 54-degree, and Project X IO 6.0 in the 60-degree wedge. This fine-tuning helps him manage spin rates on partial shots around the green. For his putter, he trusts a Scotty Cameron Phantom 9.5R Tour Prototype, gripping it with a SuperStroke Zenergy Pistol GT. All other grips on the bag are SuperStroke Crossline 2.0 Full Cord, and he plays a Titleist Pro V1 ball.
The shift from a full set of game-improvement irons to a hybrid approach signals a major step in Koivun’s development. By mixing the T250 and T100 with the 620 MB Prototype, he is bridging the gap between his collegiate success and the demands of professional competition. The use of prototypes in his woods and putter suggests he is actively engaged in the fitting process, working closely with Titleist to dial in specific performance metrics. This level of customization is rare for a rookie and usually reserved for veterans who have spent years understanding their exact needs.
His record of 2–0–1 in the Presidents Cup, highlighted by that win over Si Woo Kim, validates these equipment choices. The fact that he won his first professional title at the 3M Open right after leaving Auburn shows he has the mental toughness to handle pressure. The skepticism that surrounded his initial roster selection has now vanished, replaced by a clear respect for his game. This WITB setup proves he is not just a product of hype, but a player with a sophisticated understanding of how equipment influences performance.
With his spot on the team secured and his gear dialed in, Koivun now faces the regular season with a clean slate. The focus shifts to maintaining this level of consistency against the world’s best players week after week. His equipment choices, as detailed by GolfWRX, will likely evolve as he gathers more data on different course conditions. For now, the Titleist GT2 driver and the mixed iron set remain his weapons of choice as he continues to build his legacy on tour.
