Golfs governing bodies have passed legislation limiting groove shape and depth on iron clubs as of 2010. The Royal and Ancient Golf Club of St Andrews and the US Golf Association have passed the laws after it was discovered that clubs with deep, sharp edged, U-shaped grooves help the golfer to gain more spin from the rough when striking urethane covered balls. The changes will come into effect in 2010 in professional and amateur tournaments, though equipment made before 2010 wont be illegal elsewhere until 2024.
The changes will place an emphasis on accurate driving, with clubs ranging from wedges to five irons required to have shallower grooves and round edges. Just two of the top ten money winners on this years PGA Tour were in the top 100 for driving accuracy, so the changes should limit the effectiveness of long powerful drives.
The changes have been welcomed by World Number 13 Jim Furyk, who labelled the changes as a positive move. He said, If you can limit the amount of spin on the ball and make the guy play from the fairway and hit a more crisp and better golf shot, its probably a good avenue.
