It was fitting Mickelson gave the Augusta National patrons one last chance to roar on a weekend full of them.
With his closing birdie at the 72nd hole, Mickelson ignited yet another celebration.
Mickelson celebrated hugging his wife, Amy, who is being treated for breast cancer. It was her first appearance at a tournament since the news of her illness broke 11 months ago.
With a 5-under-par 67, Mickelson closed out a three-shot victory over Lee Westwood (71). He finished at 16-under 272.
“It’s been an emotional year, and I’m very proud of my wife and the fight and struggle she’s been through,” Mickelson said. “It’s been a difficult year and to come out on top in this tournament was very emotional.”
