So it's no surprise that Day rose to the occasion at Quail Hollow Club this week, carding four straight rounds in the 60s, including Sunday's two-under 69, to claim a two-stroke win at the Wells Fargo Championship.
"I just stayed in my lane, " Day said.
Never mind that it was the only putt he made longer than five feet.
"I was so close to shooting about 7 under on that back nine, " Woods said after shooting 34 on the closing nine holes. "I learned a lot about myself but I learned more about how much I actually wanted to get back to No. 1".
Day hit a five-foot birdie putt at the par-5 10th, a 14-footer for birdie at 12 and back-to-back two-foot birdie putts at the 14th and par-5 15th.
"That's one of the things I think he should take away from it is he did it under different conditions, different times in his life, and now he's got a taste of it, he wants it back again, " Woods said. But Watney is back healthy and playing pretty good golf, so even if he doesn't leave Quail Hollow with a trophy that can go down as a nice win.
His brilliant finish included a near hole-in-one at the par-three 17 when his seven iron shot from 200 metres hit the flag and stopped just inside a metre from the cup.
Peter Uihlein fired a sizzling nine-under 62 to be among the chasing pack tied for third.
Phil Mickelson opened with two bogeys, failing to capitalize on the momentum from his third-round 64. Save those last two holes, and he'd realistically be in contention for Sunday. Facing a delicate pitch on the next hole from about 50 yards, to a slightly elevated green with the pin on a slope, he got that to 10 feet and holed the putt.
DeChambeau, the Tour's admitted science nerd, is lurking as is 21-year old Aaron Wise, who showed his tenacity by holing a chip shot on the final hole a moment after a swing and miss from thick rough beside the green.
Day took his lone bogey at the par-4 fifth when he found a fairway bunker off the tee and came up short of the green.
After making only one on Friday - on his final green - Woods started in a tie for 48th and managed to make six birdies, including on the par-4 14th, where he drove the green from 320 yards with a 3-wood. "Didn't quite get the ball in position", Day said.
Mickelson wasn't that wild - three bogeys, two birdies, another 72, and he made the cut with one shot to spare.
The win comes after Day's victory at January's Farmers Insurance Open, his first title since the 2016 Players Championship.
"I feel like it's right on the end of the tip", he said, smiling and rubbing together the tips of his fingers. "Luckily my short game stood the test".
His drive down the 18th, where he carded an eight in the third round of last year's PGA Championship at the course, flirted with the stream down the left but it remained dry, unlike his feet as he played a solid second shot onto the green with them planted in the water. "This was probably one of the best wins I've ever had just because of how hard everything was today".
