Michael Phelps, not content with winning 18 gold Olympic medals, showcased his golfing ability at St Andrews on Friday with a mammoth 150-foot putt at the Old Course.
Phelps, who participated in a pre-Ryder Cup event at the Medinah Country Club last week, is playing with Paul Casey at the famed Scottish golf course.
