AUGUSTA, Ga. (AP) – Two months ago, Scottie Scheffler had never earned a PGA Tour victory. Today, he’s the world’s No. 1 golfer and the reigning Masters champion. Scheffler picked up his fourth victory since Feb. 13 by defeating Rory McIlroy by three strokes at Augusta National. He came into the day with a three-shot lead, and he made sure it held up by closing with a 1-under 71. Scheffler finished at 10-under 278 overall, winning for the fourth time in his last six tournaments. Scheffler four-putted for a double-bogey at the final hole, but he had such a comfortable lead it didn’t matter. McIlroy was the runner-up after shooting 64, but he came into the day 10 strokes behind and was never a serious challenger to Scheffler. The Masters is the lone major to elude McIlroy. Cameron Smith birdied his first two holes on Sunday to get within one stroke of the lead, but he fell out of contention with a triple-bogey at Amen Corner and finished five back. Smith and Shane Lowry finished in a third-place tie.
