J.J. Spaun won the U.S. Open. Big moment, career-changing stuff. But let’s be honest, the real story this week might be the irons in his bag. The Srixon ZXi7 just added a U.S. Open title to their resume, after already being named the Best Players Irons of 2025 in our MyGolfSpy testing. If you’ve been ignoring Srixon in the players’ iron conversation, now’s the time to rethink things. Here’s a full look at what Spaun had in the bag when he took down Oakmont.

What’s In J.J. Spaun’s Bag – 2025 U.S. Open Champion

Driver: Titleist GT3 (9°), Fujikura Ventus Black VeloCore+ 6 X shaft 3‑Wood: TaylorMade Qi10 (15°), Mitsubishi Diamana PD 70 TX shaft 5‑Wood: TaylorMade Qi10 (18°), Mitsubishi Diamana PD 80 TX shaft Irons: Srixon ZXi5 (4‑iron) & ZXi7 (5‑PW), True Temper Dynamic Gold Tour Issue X100 shafts Wedges: Cleveland RTX ZipCore (50°), Cleveland RTZ (54°), Cleveland RTX 6 ZipCore (60°); True Temper Dynamic Gold Tour Issue S400 shafts Putter: L.A.B. Golf DF3 Grips: Golf Pride Tour Velvet Ball: Srixon Z-Star Diamond

Driver: Titleist GT3

The GT3 finished as the runner-up in MyGolfSpy’s high swing-speed driver test; it ranked second for distance and fourth for accuracy. It offers a forward CG and lower spin, delivering fast ball speeds averaging 147.5 mph (about 3 yards more carry than its predecessor).

Fairway Woods: TaylorMade Qi10 (15° & 18°)

Spaun carries the TaylorMade Qi10 in both 15-degree and 18-degree models. These were strong performers for distance in our 2024 testing. Many tour professionals have left the Qi10 line in the bag for both the driver and the fairway woods.

Irons: Srixon ZXi5 (4i) & ZXi7 (5‑PW)

The Srixon ZXi7 was just named Best Overall Player’s Iron of 2025. It scored 9.4 out of 10, led in accuracy (9.5) and forgiveness (9.5), and ranked 7th for distance. The PureFrame design provides a crisp feel with a 9.3% vibration reduction. These irons blend tour-level performance with everyday usability.

Spaun has just proven that they work for both amateurs and professionals, and that says a lot.

Wedges: Cleveland RTX / RTX ZipCore / RTX 6 ZipCore

Spaun plays with a mix of Cleveland wedges, including the RTX ZipCore in a 50° loft, the Cleveland RTZ (54°), and the Cleveland RTX 6 ZipCore (60°). Wedge play was difficult at Oakmont with a combination of fast greens and thick rough. Cleveland wedges ranked very high for spin in our 2024 test. We will see how these perform in 2025.

Putter: L.A.B. Golf DF3

The DF3 has gained buzz for its stability and face-balanced design. When you are putting at the U.S. Open, it’s all about confidence, and the DF3 worked quite well for Spaun. It’s good to know it holds up on long-range putts. A quick replay of the 72nd hole can prove that for you.

Final thoughts

The 2025 U.S. Open was a big win for J.J. Spaun, but it’s a big win for Srixon as well. If you want to see how some of the clubs in Spaun’s bag performed in our testing, take a look here:
