 Billy Horschel has a one-stroke lead going into Sunday's final round at the British Open Golf Tournament, now underway at Royal Troon in Scotland. He shot a 69 despite rain and heavy winds that kept many players from reaching some greens on the back nine of the course. Six players are tied for second place, including PGA champions Xander Shawfully and Justin Rose. Both came from ten strokes back by shooting a 65. I'm Dale Willman, NPR News in Washington.
