The putts haven't been quite so automatic for Tiger Woods and Rocco Mediate has found a rhythm off the tee. Mediate birdied No. 13 and No. 14 as a Woods birdie putt lipped out on the Par 4 14th hole. Woods has been having trouble hitting fairways and you have to wonder how much his left knee is bothering him on the long shots. He hasn't winced noticably today very much but he did on one occasion. He is now on his 87th hole of the U.S. Open after having not walked 18 holes since the Masters on his repaired left knee.
