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.
