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.

Scottie Scheffler battled just to salvage a 71 — the sixth straight round over par in a U.S. Open for the No. 1 player — and then headed to the range with arms flailing while venting frustration on why the ball wasn't going where he wanted. He was seven shots behind and felt he was still very much in the hunt for a second straight major.

Sam Burns came into Friday knowing that he could play at Oakmont. He also knew what the course could do to him, having finished with three bogeys and one double bogey during Thursday’s opening round.
