Tiger Woods has switched to playing with a Nike Golf ball that spins slightly less and has a harder cover than the ball he was previously using. Many believe the change has resulted in Woods hitting longer tee shots than he has all year, which was evident at the AT&T National. Woods was ranked 78th for driving distance before the tournament, but after the first few rounds he lead the tournaments driving distance rankings at just over 328 yards. The change in ball is likely to be part of Woods preparation for the British Open Championship in St Andrews next week where the wind is a major factor, and with the ball spinning less this will give Woods more control around the greens.
