Hideki Matsuyama held a five-shot lead as he hit the turn in the final round of The Masters.
Matsuyama went into the last 18 holes four strokes ahead and in the box set to claim the first major title of his career.
Amid windy conditions at Augusta National, the Japanese made a shaky start on Sunday, two-putting for bogey on the first as he paid the price for a wayward tee shot.
He appeared to be in trouble again on the next after finding the bunker with his approach, but he sent an exquisite shot out of the sand to four feet and made no mistake with the putt to birdie the par-five second.
Matsuyama performed similar recovery work on the eighth. He sent his approach off the edge of the green but an excellent third shot left him with just three feet for another gain.
That restored his overnight advantage and a wondrous approach on the ninth saw that lead extended, with Will Zalatoris, who had threatened to erase Matsuyama's margin with a birdie-birdie start, struggling to keep pace.
Zalatoris, making his first competitive start at The Masters, bogeyed the eighth and the 10th but, at eight under, still stood as Matsuyama's closest challenger.
Justin Rose, Marc Leishman and Xander Schauffele had been four adrift after Saturday's play but all fell further back on Sunday.
Rose and Leishman were each five under through nine, with Schauffele within seven shots of Matsuyama on six under.
