PDW withdrew from last year's U.S. Open as well. However, that was after struggling with a pulled hamstring (I think) just to make it to the cash cut. He isn't getting any younger and that is a lot of bowling for one week. Even though the chance at 100 grand is tempting, possible permanent injury shouldn't be risked. I am glad he clarified the situation. I am sure he would have loved a shot at his 5th Open title, but it wasn't meant to be this year.
