The fans following Fred Couples and Tom Watson early Thursday morning were sometimes six- and seven-deep, wedging themselves between tree trunks and ducking under limbs. Very quietly, and without much attention, Bruce Vaughan was the player taking early control of the U.S. Senior Open. Taking advantage of cool morning conditions and mostly avoiding the canopy of trees engulfing Sahalee Country Club, Vaughan opened with a 4-under 66 on Thursday to take a two-stroke lead. http://sports.espn.go.com/golf/news/story?id=5421559
