The lowest 18-hole score ever recorded in a professional golf tournament is 55. It was achieved by Rhein Gibson on May 12, 2012, at River Oaks Golf Club in Edmond, Oklahoma. Gibson shot a course record 12-under-par 58 in the second round of the Astara Golf Championship, which was a Web.com Tour event.
Gibson’s round included 12 birdies and two eagles. He started the round with a birdie on the first hole and never looked back. He birdied the next four holes to get to 5-under par through five holes. He then birdied the ninth hole to get to 6-under par for the round. All in, the round was shaping up to be something of a record breaker.
On the back nine, Gibson birdied the 10th, 11th, 12th, and 13th holes to get to 10-under par for the round. He then eagled the 14th hole to get to 12-under par for the round. He finished the round with a par on the 18th hole to shoot a course record 12-under-par 58.
Gibson’s round was the lowest 18-hole score ever recorded in a professional golf tournament. It was also the lowest round ever recorded on the Web.com Tour. Gibson’s round was so impressive that it was recognized by the Guinness World Records.
Gibson’s round was a one-off performance. He has never shot another round in the 50s. However, his round is a reminder of the incredible talent that exists on the professional golf tour. It is also a reminder that anything is possible in golf.
