When Sam Burns stood over his tee shot on the 15th hole in the final round of the U.S. Open, he was in a tie for the lead. When he walked off the green, he was two shots back and essentially out of contention. What transpired in between is a questionable ruling that very much led to the double bogey Burns carded on the hole.
