Ryo Ishikawa is the Japanese 17 year old who has caused a stir on JPGA tour and qualified for the Open at Turnberry by winning the Mizuno Tournament in Japan...which included a 9 on the 12th hole...but an eagle chip in and a birdie to finish gave him the victory which gained access to the Open.
Seems to be swinger...interlocking grip (with weird finger looks loose?)... single wrist action on backswing...standard on downswing... great flying wedges from release through impact and beyond...
