For parts of the opening round of the U.S. Open, it was hard to tell if the players were at Shinnecock Hills in Southampton, NY or if we were seeing a glimpse into the future at Royal Birkdale Golf Club for next month’s Open Championship. Wind, rain, a two-hour fog delay, and a challenging layout made putting up low numbers extremely difficult. When all was said and done for the day, Wyndham Clark went on a heater and was 6-under before play was suspended due to darkness just before 8:30 p.m. ET.
