Johnson hit the ground in disbelief. It would turn out to be the closest he would get to victory.
"I had my chances on the back side in regulation. I mean, I hit some really good shots and just didn't make anything," Johnson said.
Hearn also had a shot at the win, which would have been his first on the PGA Tour, as well. But he missed a makeable putt on the fourth playoff hole.
"Congrats to Jordan. He's going to have an amazing career, obviously. He's an incredible talent to come on Tour at his age and have as much success as quickly as he has. So hat's off to him," Hearn said.
Spieth, Hearn and Johnson all went right on their final tee shot. Spieth scrambled out of the rough, though, finding the back of the green to save par and win his first PGA event.
Woods, Mickelson and McIlroy were all 20 when they picked up their first victories, but none of them could match Spieth, who is now the fourth-youngest winner in Tour history.
"Just got so lucky. That's what it is. But right now I'm extremely pleased, and a little worried about only having short sleeves going to Scotland," Spieth said.
