Grace's bogey-free round featured birdies at the first, third, fourth, eighth, ninth, 14th, 16th and 17th - with a crucial par save at the last securing the historic number.
Numerous golfers had carded a 63 in the four majors; there were at least two instances in each of the sport's premier events, including 10 at the British Open.
Grace, 29, is still trying to take in the enormity of his achievement in becoming the first man to break 63 in the 442 majors since 1860.
"We knew what the score was, but I had no idea I was about to shoot the lowest round ever".
Liverpool seal Robertson move
Speaking in the aftermath of the completion of the move, Robertson told Liverpoolfc.com: 'It feels a wee bit surreal just now.
He equalled the record for the lowest ever round on the European Tour when he shot a 12-under-par 60 at Kingsbarns in his 2012 victory at the Alfred Dunhill Links Championship. I thought if I could make a couple more on the back nine, then it's going to be a great score.
Johnny Miller's stunning final round at Oakmont in the 1973 U.S. Open was the first, and more than two dozen players have matched it since across all four majors. The 51-year-old won the Open in 1995. His terrible drive at the short par-four fifth flew so far left that it crashed into a grandstand and rebounded preposterously onto the green, enabling him to two-putt for a birdie.
"Zack came up and said, 'You're in the history books, ' " Grace said.
Spieth, a two-time major champion, holds a three-shot lead over Matt Kuchar, a man who has more than 80 top-10 finishes to his credit.
Chelsea a step ahead of Arsenal
Conte said, according to the Independent : "In Singapore, Rudiger and Morata will arrive, maybe someone else , I hope". It will show my commitment with the club, with this project as I try to build something important.
"You know, it's just one of those things where if it starts going bad in these conditions, it's just going to go bad". "My goal had been to score a 66 today and I bettered that by one shot".
"I'm playing some good golf, hopefully I can go out tomorrow and play well". There was a near 62 at this very course in the 1991 British Open, when Jodie Mudd set a new course record (breaking the one that Ian Baker-Finch had set just the day before with a 64), but he couldn't quite get there. His career low round in a PGA Tour-sanctioned event was a 63 at the WGC-HSBC Champions event previous year.
There have been 31 rounds of 63 in the sport's biggest tournaments and Grace's feat prompted a standing ovation at the 18th green as he saluted the packed galleries at Royal Birkdale. "Whether you guys believe me or not, I honestly didn't know", he said.
