New Mizuno drivers landed on the tour workshop at the British Masters this week at Walton Heath. Not yet scheduled for public release, the new ST190 and ST190G were listed on the USGA website as legal to play from Monday 8th October. The drivers were shown to Mizuno’s tour staff for the first time on Tuesday – with further tests scheduled away from the event. Australia’s Marcus Fraser was impressed enough to put the ST190 straight into his bag for the first round – finishing with a level par 72. A second ST190 also went into play on the PGA Tour – with a player yet to be named.
