This was going to be Tiger's breakthrough tournament, the week when he and his confidence started dating again. Instead, it turned out to be Mickelson's breakthrough performance of 2012.
"It's one of the more emotional victories for me that I've had," Mickelson said. "And the reason is that I've had some doubts these last couple of weeks, given the scores that I've shot.
So this gives me a lot of confidence and erases the doubt."
There's no way around it -- Mickelson had sort of stunk it up in the three tournaments he had played this season. There was the T-49 at the Humana Challenge, the missed cut at the Farmers Insurance Open and the T-26 at the Phoenix Open. And in each of those tournaments, Mickelson put up some ugly numbers, including a 77 at the Farmers.
He spent time with a sports psychologist. He decided to quit overthinking the mechanics of his putting stroke. He listened to Amy, who arrived here in time Friday to find her husband in full "mopey" mode during his second round at Monterey Peninsula.
"Come on now," she told him. "Cheer up. Let's go make some birdies."
And he did. His attitude did a 180. He began feeling good about himself and his game.
"Phil's a big-stage kind of guy," said Mickelson's longtime friend and caddie, Jim MacKay. "He loves playing with Tiger."
In his right hand, MacKay clutched the rolled-up flag from the 18th green flagstick. This win meant more than usual. It moved Mickelson ahead of Tom Watson and Cary Middlecoff and into ninth place in all-time PGA Tour victories. Six more wins and he passes Walter Hagen.
And he won it at Pebble, the same place where his grandfather once caddied. Even sweeter, he won it with an overpowering performance that reduced Woods to an afterthought. It wasn't a major, but on some level, it felt like it.
"I'm not that surprised, no," MacKay said of Mickelson's career final-round low at Pebble.
Did I mention that when Mickelson and Woods have been paired the past five times in the final round, Phil is 5-0?
"Before, I got spanked pretty good," Mickelson was quick to remind everyone. "Let's not forget the big picture here. I've been beat up."
Now it's Woods who is the nail, and Phil the hammer. On Sunday, Mickelson hammered the entire field.
"But it could change in one week," Mickelson said. "Watching him play today, it's going to change in one week.
I know the score wasn't what he wanted and I know he didn't putt the way he wanted to, but you could tell that he's really close and all it takes is one week."
I believe him. The question is, does Tiger believe him?
When Mickelson's final putt dived into the hole, Amy stood behind the 18th green. She pumped her right fist, clapped her hands and then waited for her husband to walk down the path leading to the scorer's trailer.
They hugged behind the giant scoreboard and Amy spoke in Mickelson's ear for a full 10 seconds. Smiles all around.
"I'm a happy girl," she told CBS' David Feherty.
This is what it looks like after a career-defining victory. One of these days, maybe Tiger will know the feeling again.
