But he said he still wouldn't have played the par-4 18th hole any differently Saturday in the third round of the PGA Championship.
One day after Tiger Woods matched the major championship scoring record with 63, Weekley had a 30-foot birdie putt attempt for his own 63. He misread the break, left his first putt 8 feet short, then missed that one for a three-putt bogey and 65.
However, it was the best round of the day and put Weekley into a tie for ninth at the time he finished, at even-par 210.
Weekley was on his game on Southern Hills' back nine, making five birdies in a seven-hole stretch, including a putt from off the fringe from 15 feet for birdie at No. 14. The rest of his birdie putts were in the 8-foot range.
"He's a great ball-striker," said Brett Wetterich, who was playing one group ahead of Weekley. "Once he gets going, it's fairways and greens."
Weekley's 8-foot birdie putt at No. 17 gave him the chance for 63 at No. 18.
He said later he had no idea that 63 would have matched the major championship record, despite the hype of Woods accomplishing that feat less than 24 hours before.
"I didn't know," Weekley said. "That would have been nice."
When asked whether he would have hit the putt any different had he known what it was for, Weekley said: "Probably not ... I was just trying to play enough break and get it on top of the ridge there and roll out to the hole. I moved my big head and flubbed it a little with the putter."
Although the 34-year-old Weekley had a long road to the PGA Tour (he won his first pro tournament in 1997, an Emerald Coast Tour event, earning $2,200) Weekley is proving to be a quick study in golf's biggest events.
Since winning the Verizon Heritage at Hilton Head, S.C., in April, Weekley has made the cut in The Players Championship, the U.S. Open, the British Open and the PGA - all in his first career starts in those events.
Weekley said he's storing up a body of knowledge about how to play in such events before his first Masters Tournament next April.
"I've learned in the majors that par isn't a bad score," he said. "It's not like a birdie-fest at every course. I'm learning about how to accept just making pars."
With a good round today, Weekley can improve his standing on the Tour's FedEx Cup points list and money list even more. He entered the week 17th in FedEx points and 19th in earnings, with slightly more than $2 million.
Weekley also knows that playing as well as he is this year will enable him to realize his dream of retiring early to a life of hunting and fishing along the Blackwater River near his hometown.
"I want to play 10, 12 years, whatever it takes to get money in my bank, and I'm done," he said. "I love the game but I get tired of the grind."
When reminded that golfing legend Sam Snead once said that he played golf only so he'd have enough money to hunt and fish, Weekley replied: "Sounds like Sam and I have a lot in common."
