Woods finished alone in fourth place at 9-under par, two shots back of winner Sean O'Hair. For the week, he hit just 44.6 percent of his fairways, although he hit only 36 percent during an opening-round 65.
'The other shaft did not quite work out for me,' said Woods during Monday's U.S. Open Media Day teleconference. 'It wasn't what I was looking for. It felt good during the practice round but in the tournament, I didn't quite have the same feel for it, so I went back to my old driver on the weekend. I hit it a little bit better. But still, this driver has done pretty well, and that's the one I'll continue working with and hopefully get my swing organized.'
