23-year-old becomes youngest man in PGA Tour history to fire sub-60 round

"My birdies were all very easy and I just had a lot of good luck and kept leaving it in the right spots."

Justin Thomas made history by becoming the youngest man to record a sub-60 round on the PGA Tour after carding a magnificent 11 under par 59 on the opening day of the Sony Open in Hawaii.

The 23-year-old American registered two eagles, eight birdies and a solitary bogey in Honolulu, as he became only the seventh man to break 60 on the PGA Tour.
