Spaun’s bag starts with the Titleist GT3 driver at 9 degrees of loft, paired with a Fujikura 2024 Ventus Black VeloCore+ 6X shaft.
This combination provides the controlled distance and accuracy that Spaun needed for superior course management at Oakmont.
The GT3’s adjustable weighting system allows him to fine-tune ball flight characteristics while maintaining the consistent draw bias that suits his natural swing tendency.
The Fujikura 2024 Ventus Black shaft provides the extra-stiff flex profile that complements Spaun’s smooth tempo, delivering optimal launch conditions across varying course setups.
This shaft’s low-launch, low-spin profile perfectly matches Spaun’s naturally penetrating ball flight, helping him achieve optimal distance while maintaining control in windy conditions like those frequently encountered at major championships.

Spaun uses the TaylorMade Qi10 fairway woods with 15-degree and 18-degree lofts.
The 15-degree 3-wood features a Mitsubishi Diamana PD 70TX shaft, while the 18-degree 5-wood utilizes a Mitsubishi Diamana PD 80TX shaft.
This dual-fairway wood approach provides precise distance gapping and versatility for different course conditions.
The Qi10’s advanced carbon crown construction redistributes weight low and back, promoting higher launch with reduced spin for optimal carry distance.
The Mitsubishi Diamana PD shafts feature a firm tip section that provides exceptional control during aggressive swings, while the softer mid-section helps generate effortless clubhead speed.
Spaun’s choice to use progressively heavier shaft weights (70g to 80g) creates a nice transition in feel from his 3-wood to 5-wood, allowing him to maintain consistent tempo and strike quality regardless of which club the situation demands.
