Duvall is back on the face of the earth. Eligible for the Open because he is a past champion, he shot even par the first two days to make the cut. Today, he had a 67, which was the same score shot by two of the leaders in the tournament. He's tied for 33rd, seven strokes behind the leaders. That puts him ahead of a lot of big name pro players. I'd like to see him regain his competiveness.

John Daly missed the cut by one stroke. Another golfer whose decline was rather quick.

Another golfer that "disappeared" was Anthony Kim.
