Bubba Watson finished with an even-par 70. "It's playing just a touch easier I guess, not as dramatic scores as everybody is predicting," said Watson of Oakmont. "Every tournament you play in, no matter if it is the U.S. Open or in Memphis last week, the courses always get tougher as they go along -- no matter what they say they are trying to do."
