SOUTHPORT (REUTERS) - South Africa's Branden Grace shot a blistering round of 62, the lowest ever in a men's Major championship, as the players made hay in benign conditions at the British Open on Saturday.
Grace, the world No. 35, picked up eight birdies in a flawless third round to move to four-under par, two shots behind leader American Jordan Spieth.
There have been 31 rounds of 63 in Major championships and Grace's feat prompted a standing ovation at the 18th green as he saluted the packed galleries at Royal Birkdale.
"I honestly had no idea that was something historic," Grace told reporters.
"I knew I was playing well and I was just in the zone. I didn't know 62 was the lowest ever, but now it makes it even more special. If my caddie knew, he never said anything; good on him!"
American world No. 1 Dustin Johnson also made a significant move up the leaderboard by collecting six birdies in his first 15 holes to get to three under.
Heavy rain and swirling crosswinds had made scoring difficult in the second round, but the sun came out on Saturday morning and the world's top players took full advantage.
Local favourite Tommy Fleetwood, the world No. 14, gave the home fans something to cheer about with a fine round of 66 and former world No. 1 Jason Day of Australia shot a 65 to move to level par.
Spieth, the world No. 3 and two-time Major champion, will tee off in the final group out with compatriot Matt Kuchar, who trails him by two shots.
England's Ian Poulter is in the penultimate group alongside American Brooke Koepka with both players on three-under par.
