And on a thrill-a-minute Sunday at Augusta National, where Louis Oosthuizen of South Africa made only the fourth double eagle in the 76-year history of this major, it made Watson a Masters champion.
"I've never had a dream go this far, so I can't really say it's a dream come true," Watson said. "I don't even know what happened on the back nine. ... Nervous on every shot, every putt. Went into a playoff. I got in these trees and hit a crazy shot that I saw in my head, and somehow I'm here talking to you with a green jacket on."
His amazing shot in the playoff settled 10 feet from the hole, setting up a simple par for the win.
Lost in all the commotion was Oosthuizen making what is commonly called the rarest shot in golf an albatross when his 4-iron from 253 yards on the par-5 second hole landed on the front of the green, took the slope and rolled some 90 feet into the cup for a 2.
Oosthuizen had never made a double eagle in his life.
His Masters ended by watching a shot he didn't know existed.
After hitting short of the 10th green in the playoff, he was in the fairway and could see only a trail of fans leading into the woods.
"I had no idea where he was," Oosthuizen said. "Where I stood from, when the ball came out, it looked like a curveball. Unbelievable shot. That shot he hit definitely won him the tournament."
Watson, who made four straight birdies on the back nine and closed with a 4-under 68, made it all sound so simple. Maybe it's because he has hit so many shots like that before. Maybe it's because he is one of the few players who doesn't have a swing coach, and never has.
"Hooked it about 40 yards, hit about 15 feet off the ground until it got under the tree and then started rising," Watson said. "Pretty easy."
The hard part was holding back tears.
He was blubbering hard on the 10th green, shoulders heaving and face contorted, for so many reasons. Just two weeks ago, he and his wife adopted a baby boy, Caleb. The first person on the green was his mother his father died right after the Ryder Cup in 2010. He held her tight and cried some more.
As incredible as it all seemed, Gerry "Bubba" Watson Jr., the powerful 33-year-old lefty with a million shots at his disposal, was a major champion.
"I never got this far in my dreams," Watson said in Butler cabin, where defending champion Charl Schwartzel helped him into the green jacket. "It's a blessing. To go home to my new son, it's going to be fun."
Watson, dressed all in white and using a pink driver, had hooked his tee shot on the 10th into the trees, and it appeared he would have no shot at reaching the green.
Walking down the fairway toward an uncertain lie, he and caddie Ted Scott recalled their credo "If I have a swing, I've got a shot."
