"He did it with his ball-striking". Gary Player, who was only the third golfer in history to win the career grand slam after Ben Hogan and Gene Sarazen, won nine majors including three Claret Jugs.
There will surely be unresolved debate about what's better, a 62 on a par-70 course or a 63 on a par-72.
Following Grace's men's major record round today, Miller did the best he could to take it in stride and compliment Grace's stellar round.
Grace, 29, a South African who has seven European Tour titles and another on the PGA Tour, made eight birdies and no bogeys Saturday during the third round of The Open, which was played under mostly sunny skies and with little wind. That was Jack Nicklaus in the opening round. They include multiple major winners such as Raymond Floyd (four), Nick Price (three), Greg Norman (two), Payne Stewart (three), Vijay Singh (three), Jose Maria Olazabal (two), Mark O'Meara (two), Rory McIlroy (four) and Mickelson (five).
American Brooks Koepka, the US Open champion, went round in 68 to finish at five under, level with 20-year-old Canadian Austin Connelly who continued his remarkable run at his first major with a 66.
Miller, an Open Championship victor at Royal Birkdale as well, was on the broadcast for Grace's 62, and in classic Johnny Miller fashion, added his own set of qualifiers to the record-breaking round, including calling the course setup "really easy".
"Peter Crouch was!" came the witty reply from one man among the press pack. A 29 going out matched Grace's age.
"I don't know who was in here before me", said a bemused Fleetwood. Rasego did, but had said earlier, "I don't do interviews". "You know, I was just so in the zone of playing, hole after hole".
It's moving day at the Open today and England's Ian Poulter will be hoping to still be in the mix when his third round finishes later.
The 23-year-old calmly collected three birdies on the front nine and with Kuchar keeping pace, the pair kept the rest of the field at arm's length.
"So for me there's a lot of positives to take from this week".
