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.
JJ Spaun Wins U.S. Open with Best Player’s Iron of 2026
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.
