By Larry King TROON, Scotland, July 16 (Reuters) – Henrik Stenson will start the final round of the British Open leading the championship, and trying not to think about how it’s going to end. “Thoughts of outcome are never really helping you,” he said at a news conference after his third round at Royal Troon, where he gained a one shot advantage over American Phil Mickelson. There’s no question about it.” Stenson’s one-shot lead puts the 40-year-old Swede as close as he’s ever been to winning his first major.
