NEWTOWN SQUARE, Pa. (AP) -- Tiger Woods has switched to a Nike golf ball that has a slightly harder cover and spins less than his previous model, which might explain why he has been hitting his tee shots farther than he has all year.
Woods says his swing has something to do with it, too.
"The more I keep playing, the better I get," Woods said Saturday after recovering from an atrocious start to shoot even-par 70, making up little ground in the AT&T National. "It has a little bit to do with the ball."
Woods still uses a One Tour, this ball marked with a star symbol between the two words. He started using it this week at Aronimink, most likely as part of his preparations for the British Open in two weeks at St. Andrews, where the wind is often a major factor.
The world's No. 1 player often has talked about how he uses one of the softest golf balls on tour, which gives him greater control around the greens. This version would be helpful in windy conditions because it spins less.
Once among the longest hitters in golf, Woods was 21st in driving distance last year. Going into the AT&T National, he was ranked 78th based on two measured drives per round. Through two rounds on a fast, firm Aronimink course, Woods was leading the tournament in driving distance at just over 328 yards.
His additional length was most evident during the second round, when he was playing with Dustin Johnson. On consecutive holes, Woods hit one drive 26 yards past Johnson, and another 10 yards past him. Both led to birdies.
It continued on Saturday.
"Wow," Scott McCarron whispered when Woods hit one driver 322 yards down the middle on the fourth hole, 37 yards beyond McCarron.
The only trouble this week is that it's not helping with his scoring. Woods remained well back in the pack at 3-over 213, which left him 10 shots behind even before the leaders teed off.
