The anticipation had been building the last few weeks for the PGA Championship, just like it was for the Masters. And just like the last major, the hype was more about who played than who had a chance to win.
Tiger Woods not only played Augusta National, he made the cut.
Phil Mickelson won't even make it to the first tee at Southern Hills.
Six days before the opening round on the classic course in Tulsa, Mickelson decided not to defend his title and extend his three-month hiatus from golf.
And to think it was just one year ago when Mickelson celebrated one of the most stunning feats in 161 years of the majors. He won the PGA Championship at Kiawah Island at age 50 to become golf's oldest major champion.
The last PGA champion who didn't defend was Woods in 2008 as he recovered from reconstructive surgery on his left knee. Before that it was Ben Hogan in 1949, who was nearly killed some four months earlier when a bus hit his car in west Texas.
Mickelson's injuries were more self-inflicted. He kept everyone guessing when he signed up for the PGA Championship on April 25, even if it was a matter of procedure. His manager said Lefty was merely keeping his options open, and then he shut them on Friday.
"I personally think it's an unbelievable mental challenge to come back and play after what he's put himself through. I don't think it's as easy as just getting back on the bike and arriving at a golf tournament and playing," said six-time major champion Nick Faldo.
Mickelson is sure to be a topic one way or another. Alan Shipnuck's unauthorized biography on Mickelson is to be released on Tuesday.
His public image took a beating in February when Shipnuck published an excerpt of his book in which Mickelson outlined his involvement with a Saudi-funded rival league.
He was dismissive talking about the killing of Washington Post columnist Jamal Khashoggi and Saudi Arabia's human rights record, saying it was worth getting involved if it meant having leverage to change how the PGA Tour operates.
Top sponsors dropped him, Mickelson released a statement that read more like an explanation than an apology, and he said he "desperately" needed time away.
Now it's a matter of when he returns. His absence figures to be glaring, one of several subplots to a major that is sure to provide intrigue even before the first shot is struck.
Woods hasn't declared for certain that he will play another major, though he was in Tulsa last week to play -- and walk -- a practice round, and it would be a surprise if he didn't play. Woods won the PGA Championship at Southern Hills the last time it was there in 2007.
Woods has cast such a huge shadow on the sport for so long that it's easy to overlook the strongest field of the four majors and who might best have a chance of hoisting that 27-pound Wanamaker Trophy.
Masters champion Scottie Scheffler has a long way to go, and while he rarely thinks about anything beyond the next shot, he likely is aware only three players in the last 20 years have won the first two majors of the year.
Even so, he has everyone's attention with his four big titles in the last four months that have taken him to No. 1 in the world.
Jordan Spieth is chasing the career Grand Slam. This is his sixth shot at the Wanamaker Trophy since he picked up the third leg at the 2017 British Open, and it might be his best chance. His swing is getting closer to where he can trust it, and his confidence was boosted by his playoff win at Hilton Head a month ago.
Spieth and Justin Thomas stopped by Southern Hills at the start of the week. Spieth last played it in 2009, when he lost in large playoff for the final four spots of match play in the U.S. Amateur. He shot 75. He was 16.
Southern Hills is hosting its eighth major since 1958 -- three U.S. Opens -- and the last five champions are in the World Golf Hall of Fame.
