TPC Sawgrass's 17th hole on the Stadium Course — a 137-yard par 3 whose green is entirely surrounded by water, so a miss in any direction costs a penalty stroke rather than a lost cause in the rough. Architects Pete and Alice Dye didn't plan it that way: after mining the surrounding sand to build the course, the leftover pit filled with water, and Alice suggested leaving the green on the remaining sand island rather than filling the hole back in. The putting surface runs roughly 78 feet front-to-back with a small bunker cut into its front edge, ringed by water about four feet deep. As the dramatic closing par 3 of The Players Championship, it turns a mid-to-short iron into one of the most psychologically loaded shots in professional golf.
