AUGUSTA, Ga. (AP) — Scottie Scheffler looked like a Masters champion even before he slipped into his green jacket, the model of calm as he methodically worked his way around the most stressful course in major championship golf.

Sunday morning was different. That turned out to be the toughest test he had all day.

“I cried like a baby this morning. I was so stressed out. I didn’t know what to do,” Scheffler said after winning his first major. “I was sitting there telling (wife) Meredith, ”I don’t think I’m ready for this … and I just felt overwhelmed.”

And then he capped off his torrid two-month stretch with his grandest feat of all, leading the entire weekend and strolling to a 1-under 71 — with one lapse in concentration at the end when it didn’t matter — for a three-shot victory over Rory McIlroy.

For a guy who had won three of his previous five tournament, who reached No. 1 in the world, why suddenly be overcome with doubt?

“I think because it’s the Masters. I dreamed of having a chance to play in this golf tournament. I teared up the first time I got my invitation in the mail,” Scheffler said.

“If you’re going to choose a golf tournament to win, this would be the tournament,” he said. “You don’t know how many chances you’re going to get. And so having a chance — I had a five-shot lead on Friday and then a three-shot lead going into today — I don’t know if you get better opportunities than that. You don’t want to waste them.”

He felt peace between the ropes and never allowed himself to enjoy the moment until he took that famous walk up the 18th green, his ball 40 feet away and a five-shot lead.

“And you saw the results of that,” he said with a laugh at his four-putt double bogey that only affected the margin of victory.

McIlroy holed out from the bunker on the final hole for a record-tying final round of 64. That pulled him within three shots, and his only hope for the final piece of the career Grand Slam was for the Sunday pressure at Augusta National to get to Scheffler.

No chance.

Not on Sunday. Not the last four days. Not the last two months.

“You get on those hot streaks, and you just got to ride them out because they, unfortunately, don’t last forever,” Justin Thomas said. “But he is doing it in the biggest tournaments. … It’s really, really impressive to see someone that young handle a moment this big so easily.”
