Grace added: "It's special, it really is".
Kuchar felt a similar sentiment.
But the player that is showing the most value heading into the final round?
Kuchar said that he played well and was pleased with his 66 - and why wouldn't he?
He was nervous on the first tee, not quite believing how many spectators were watching him.
Following the resumption of the second round, the two-time major victor got himself back in to the groove, collecting back-to-back birdies at the 11th and 12th before an eagle at the 15th, either side of two further bogeys.
Every stroke is important, as a lot will be on the line in the final round at Royal Birkdale. Teeing off just before Spieth, the Northern Irishman holed three birdies from his first give holes, including an exquisite 20 yard chip on the second to jump to four-under par.
Six behind the leader, the US Open victor will have to play the round of his career to catch Spieth.
He has not ruled out making the Open Championship his first victory on a major worldwide tour after battling to remain in contention. The vile vegetation of its rough, fattened up with the blankets of rain that came Friday, lacked golf balls to devour, so true were so numerous unburdened shots.
"I've always been good, when I get off to fast starts, being able to keep it going", he said, "and I didn't today".More news: OJ Simpson could soon walk free as he faces Nevada parole board
"[But] I definitely feel like today was an opportunity lost to get right in the mix".
As with that 2016 Masters, the only person that can truly take down Spieth is Spieth himself. Spieth clenched his fist when it dropped for birdie, and then Kuchar missed from about 12 feet.
RIGHT: Jordan Spieth rolls in his fifth and final birdie of the day on the 18th hole.
Connelly birdied his last two holes for a 66 on Saturday, leaving him six shots out of the lead and in the penultimate group with U.S. Open champion Brooks Koepka.
"It's tough to make putts when you're not that close to the hole". He has just four bogeys this week, and all of them came in Friday's downpours.
Johnson looked like he might have a chance to match Grace's 62, which set a record for low score in a major championship.
Spieth's 54-hole total score of 199 is just one shot shy of the British Open record held by Tom Lehman when he went on to win at Royal Lytham and St Annes, just up the north-west English coast, in 1996. "It's a day where you had to be aggressive".
By the time this Jordan Spieth finished on Saturday, the 123-year-old course, one day after a bonanza of brutality, would reel with the first 62 in the 442-event history of men's major golf - by 29-year-old South African Branden Grace - as well as a 64, five 65s, eight 66s, seven 67s, eight 68s and 13 69s. That followed a spell of torrential rain on Friday night, though soft conditions weren't the sole reason for this scoring spree.
Bogeys on the seventh and eighth took the wind of out his sails, however, and on the 10, his championship hopes took a sizeable blow after he bunkered from the fairway. "No surprise", said Zach Johnson, victor of the 2015 Open Championship. And some of the best rounds of major round golf were completed just hours ago.
Similar to his countryman, Scott Hend also shot a 65 and likewise catapulted 43 spots for a share of 18th place. The forecast calls for some sunny spells during the afternoon with only a 20 percent chance of showers. The high temperature is forecast to only reach the mid-60s.
