New Mizuno ST-Z and ST-X 230 drivers added to the conforming list
First testing spotted at The British Challenge / St Mellion
The USGA has approved and added Mizuno’s 2023 drivers to its conforming list. The new ST-Z and ST-X 230 drivers are now eligible to play on tour. The ST-Z was being heavily tested at the Mizuno supported British Challenge in St Mellion. Both Mizuno’s OJ Farrell and Marco Penge are believed to have taken the new drivers away after successful testing.
The new driver features Mizuno’s CORTECH Chamber – engineered to deliver more ball speed across the face, as well as reducing spin rates.
The driver is expected to be released to the public early in 2023. More info to follow.
