Tiger Woods has backed a decision by the PGA Tour to bring forward by a year new rules that limit grooves on irons.

The move was due to be made in 2011 but US PGA Tour commissioner Tim Finchem but the ruling will now take effect from next year.
The changes are aimed at limiting the amount of spin players get from shots out of the rough, placing the emphasis more on accuracy.
And Woods says the players have had plenty of time to get used to the new club faces.
""It's great,"" said the world number one. ""We've had plenty of time to make our adjustments.”
