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.

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.
