Of course Day also had to deal with a lot of other issues in the a year ago and a half, including his mother's battle with cancer, a miscarriage suffered by his wife, Ellie, and a nagging back injury.
Before that, we will get the privilege of watching both men striding side by side at Sawgrass tomorrow and Friday, at a time in life where they retain enough of the magic to suggest there are one or two golden days still ahead.
You talkin' to me?
"I think [it] has certainly gotten a lot closer with me being a vice captain the last couple teams and sitting there and having very lengthy conversations with him about things", Woods said.
Mickelson mentioned in a magazine interview going into the 2003 season that Woods used "inferior" equipment.
"We've always had a mutual respect over the years, and I've always appreciated what he's done for the game of golf", Mickelson said Tuesday. "I said, 'Yeah, you and I have the same philosophy in how we approach chipping and how we do it". He won the tournament again in 2013, which happens to account for his PGA Tour exemption status this year. "As I look at the cover of the newspaper and the pairing is on there, and the excitement that has been going on here, it gets me thinking, why don't we just bypass all the ancillary stuff of a tournament and just go head-to-head and just have kind of a high stakes winner-take-all match?"
"I'm just not that comfortable with anything right now. You know, there was a stretch there of a number of years that it was so impressive that it was hard to imagine that it was actually happening, that he was hitting some of the shots that he was hitting and playing that well". A month later he won the Open Championship by eight, becoming the youngest to complete the career Grand Slam at 24.
"I had all four major championships", he said.
Mickelson called it the greatest golf that "has ever been played". To hold all those events concurrently was special.
He would make solid pars on 11, 12, 13 and 14, including a 14-footer for par on 14-by far his longest made putt of the day-but three-putted from inside 20 feet to drop to three over.
Not surprisingly, his legend follows him even today. Fowler says he'll try and putt out first, when he can, to avoid potential distractions. The same goes for Spieth and Thomas.
"When I was trying to deal with my back and try to come back and wasn't very good, he always texted me some really encouraging words". And the third guy is sure to generate a lot of interest as well because it's Rickie Fowler.
Throughout the duo's careers, the general consensus has been that there was some sort of animosity between them that went beyond the normal competitive fire.
