Sam Burns fell apart during the final round of the U.S. Open at Oakmont on Sunday, and a controversial ruling on No. 15 may have contributed to his collapse.

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.

Sam Burns was forced to hit out of a soggy lie on the fairway of the 15th hole of Sunday’s final round at Oakmont after asking two rules officials to take a drop.
