It's like a joke: An Olympic swimmer, a top-ranked golfer and an MVP baseball player take to the golf course. Only difference is there's no punchline because this is real. Michael Phelps, Jordan Spieth and Bryce Harper took to the links to stay loose and probably talk about how they are so incredibly physically gifted.
Woe be to the person who was thrown in to complete this foursome. It would be like a mortal approaching Mount Olympus. Though, at the very least, I assume Bryce would be able to give a great piggyback ride when their legs got tired on the back nine.
