Joel Achenbach explains Tiger’s miracle shot:
What few people realize is that this is all done with powerful magnets. Augusta National has the most advanced electronics underneath its greens of any golf course in America. There’s essentially an entire city down there, with technicians in jump suits, hallways as long as a Par 5, enough computing power to track a fleet of satellites. In fact they use GPS to guide the ball into the hole. Basically all Tiger had to do was get the ball somewhere on the green — anywhere. Although he hit a terrible shot and came nowhere close to the hole, the folks in the bunker took over and guided the ball home.
Achenbach goes on to explain that this was because Tiger’s success is more critical to the television networks and corporate sponsors than Chris DiMarco’s.
