HOYLAKE, England : Brian Harman, a keen hunter back home in Georgia, simply refused to allow himself to fall prey to the world's leading golfers as he showed nerves of steel to win the British Open on Sunday.The 36-year-old American led the tournament by five shots after rounds two and three and by the end he was six clear of his closest challengers."So pleased with the way I hung in there the last couple days," Harman told reporters. "Got off to a bad start both days and turned it around, so really happy with that."Rory McIlroy and Jon Rahm, the world numbers two and three, were among a pack of players who failed to reel Harman in, squandering opportunities when the world number 26 wobbled on a couple of occasions.Starting his third round shortly after Rahm had completed a course-record 63, Harman dropped two shots in his first four holes.He was not rattled, however, and a birdie at the fifth was followed by another at the ninth to quickly repair the damage.Two more birdies followed on an error-free back nine to complete a round of 69 and restore his five-shot advantage."It would have been really easy to let the wheels start spinning and really kind of let it get out of control," he said."But I just kind of doubled down on my routine and knew I was hitting it well."In heavy rain on Sunday, Harman again made two early bogeys and, with McIlroy off to a fast start with three successive birdies, the Hoylake galleries sensed that the leader might be wilting at last.SMOOTH PUTTSBut Harman responded quickly, sinking smooth birdie putts on the sixth and seventh greens to bolt the door shut for the last time.He negotiated the back nine without major alarms until he found one of the notorious pot bunkers around the 18th green.The
