Branden Grace re-wrote golf's major record books on day three of the Open Championship at Royal Birkdale by shooting the first round of 62 in a major championship.
Grace, 29, started the day on 4-over and raced through the pack all the way up into Open contention on 4-under in a tie for fifth and six shots behind leader Jordan Spieth.
The South African went out in 29 shots thanks to five birdies and returned with three birdies on the 14th, 16th and 17th for a round of 8-under 62.
Grace found the back of the green at 18 and cosied his putt up to within two feet to achieve a remarkable feat.
"It feels great now, I didn't know to be honest," said Grace.
"Zach (caddie) said congrats man, and I said thanks. But had no idea I had got the lowest ever round in a men's major!
"I played really solid from tee to green. Missed a couple of short ones. It was a good day."
The previous record for the lowest round ever shot in a men's major championship had been 63 - a score recorded 31 times in each of the four men's majors.
The lowest ever score in a major championship is 9-under, however. A score achieved by Nick Price (1986 Masters), Greg Norman (1996 Masters), Justin Thomas (2017 US Open), Paul Broadhurst (1990 Open), Rory McIlroy (2010 Open), Gary Player (1984 US PGA), Jose Maria Olazabal (2000 US PGA), Hiroshi Iwata (2015 US PGA).
