On a typical Thursday at 10:30 a.m., John Singleton would be making paints and varnishes in a resin factory. Maybe driving around in a forklift truck.

Not this Thursday morning.

On this one-off occasion, Singleton was 10 minutes down the road at the British Open at Royal Liverpool, whipping up the crowd on the first tee before taking the biggest - and most nerve-wracking - shot of his life.
