Keith Mitchell goes from lows to highs in record-setting turnaround at US Open‎

Most astounding about Keith Mitchell was doing it in just over two hours. Mitchell set a U.S. Open record Thursday at Shinnecock Hills when he became the only player to post a score in the 40s on nine holes, and follow that with a score in the 20s on the next nine. It added to an even-par 70, and Mitchell still isn't sure what happened.
