Brian Harman knew Saturday evening that sleep might be hard to come by, as much as he knew he needed it. He had been here — the 54-hole leader at a major tournament — six years ago and knew the agonizing cost of a fitful night: a runner-up finish, months and then years of what-ifs, a career not on the margins but not among the elite.
He slept well enough this time. Harman, nestled atop the leaderboard at Royal Liverpool Golf Club since Friday, made a methodical march Sunday to win the British Open by six strokes.
