 Xander Shoffley walked off the 18th green at Royal Troon in Scotland and knew he had a healthy lead. Now, he didn't know for sure at that moment that there would be no one who could catch him. I think there was one other golfer who had a shot, had to make a birdie putt, and then eagle the following hole, which would have been, well, nothing short of a miracle. But Xander was pretty confident in the way he finished, and wow, what a final round for him.
