Charl Schwartzel immediately set his sights on a second Major Championship title after equalling the lowest round in US PGA Championship history on day two at Bellerive Country Club.
On a history-making morning in St Louis, first Brooks Koepka became the 15th player to record a 63 at the season's fourth Major and then Schwartzel became number 16, with both men having putts to match Branden Grace's all-time low for all Majors of 62.
It was only the second time that two men had signed for 63s on the same day at one of golf's big four events after Tom Weiskopf and Jack Nicklaus in the second round of the 1980 US Open.
When the dust settled, however, South African Schwartzel was more focused on adding a second Major title to his 2011 Masters win than he was on his incredible performance.
"I'm looking forward to playing on the weekend and competing in a Major," he said. "It doesn't get better than that.
It's about time. There's been ups and downs and I just feel like I'm starting to play a better golf game - Charl Schwartzel
"It's a good position to be in and there's a lot of holes to be played. I think on this golf course, you're going to have to keep firing. Most Majors, the weekends get difficult, but I think this course you're going to have to keep shooting birdies.
"It's about time. There's been ups and downs and I just feel like I'm starting to play a better golf game."
A hot putter handed Schwartzel a birdie-birdie start but he bogeyed the sixth before bouncing back with birdies on the seventh and eighth. The 33 year old made a hat-trick from the tenth and a stunning tee-shot on the 16th set up a birdie and his chance at history from 50 feet on the last.
"In the practice rounds, I thought you've got a good chance of shooting a low score," he said.
"I was hitting a lot of drivers. If you're hitting it down in the fairway with the way the greens are designed, you can get the ball to about 15 feet on almost every hole.
"I think this morning was very scorable. I drove it decently well for me and my iron play has been really good. So I gave myself just a lot of chances. I felt like I was putting for birdie on pretty much every hole."
Thomas Pieters was alongside Schwartzel at seven under after he fired the lowest round of his Major career with a 66.
The big-hitting Belgian was bogey-free, making nine pars on his first nine before birdieing the first, fourth, seventh and eighth.
"I feel good," he said. "I've been driving it very well.
"I stayed patient on the greens. Hit nine greens in regulation on the first nine holes and didn't make anything, so it was very frustrating. But I made some really good putts. It's good.
"If I just keep playing the way I am, we'll see what happens on Sunday, but if I keep driving it like this, I'll give myself a good chance."
