55. Rhein Gibson (Australia) earned the lowest golf score (male) on an 18-hole course on May 12, 2012, at the River Oaks Golf Club in Edmond, Oklahoma, USA. The River Oaks course is 6,700 yards long and has a par of 71. Gibson shot his round in just over three hours using a driver, fairway wood, iron, and putter. He started the day with a career low 153 rating on the scale used by the United States Golf Association to measure performance, and ended it with a 10-under-par 62. The previous record was held by David Graham (England), who scored 56 during a practice round for the 2004 Open Championship.
The lowest official men's score on an open tournament was also set by Gibson. He equaled this mark during the 2012 Australian Open.
Gibson was one of several players to have rounds of 62 or lower during the 2012 Australian Open. He along with Jason Bohn, Lucas Herbert, Marc Leishman, and Michael Weaver are the only ones to have achieved this feat more than once. The last time four players had rounds of 62 or lower in the same tournament was at the 2007 Masters Tournament when Ernie Els, Fred Funk, Matt Kuchar, and Ian Woosnam all shot scores of 62. This is the only instance where four players have shot identical scores into a major championship round.
Approximately 72 A conventional 18-hole golf course has a total par of roughly 72, whereas a 9-hole par-3 course (with all holes classified as par 3) has a total par of 27. An 18-hole "super" course with different lengths of holes and varying degrees of difficulty would have a total par of approximately 90.
The United States Golf Association (USGA) maintains the database on which this information is based. They define an "average" course as one with four or five sets of tees, each set representing a different level of difficulty. They say that these levels are designed so that no more than 25% of players will play at any one time at too difficult a level to be worthwhile playing. Thus, only one-fourth of the rounds will involve playing at a very difficult level, one-fourth at a difficult level, one-fourth at an intermediate level, and one-fourth at a very easy level.
This means that on average, one out of every four rounds played will be at a very difficult level, one out of every four rounds will be at a difficult level, one out of every four rounds will be at an intermediate level, and one out of every four rounds will be at a very easy level.
It also means that most people will play courses that are neither very easy nor very difficult.
Here are his lowest PGA Tour stroke totals in 72-hole tournaments: Let's take a look at the other end of the spectrum—the lowest and greatest scores Woods has ever shot on the PGA Tour and in majors. Woods had a PGA Tour score of 77 or above eighteen times in his professional career. His lowest round on the tour was a 67 at The Masters in 1996, one year after it adopted a par 72. He also had a 66 at the U.S. Open in 1999.
Woods' highest round is a 5-under 67, which he shot to win the Buick Invitational in March 2004. That was his third victory that season and ninth overall on the PGA Tour. The tournament was then down to its final hole when Jeff Sluman hit a fairway metal into the rough off the tee of the 18th hole. A group including Woods stopped on the first tier of an amphitheater-like seating area and began tossing balls toward the hole as if they were horseshoes. When no one claimed them, they were awarded to Woods and Dave Stockton, who had tied for first place. Stockton would go on to lose to Woods in a sudden-death playoff for their first prize money of $750,000.
Woods' 4-under 68 in the final round of the 2005 Masters led to him becoming the first player to win both the Masters and United States Open in the same year.
