Hideki Matsuyama delivered golf-mad Japan the grandest and greenest prize of all. Ten years after Matsuyama made a sterling debut as the best amateur at Augusta National, he claimed the ultimate trophy Sunday with a victory in the Masters to become the first Japanese winner of the green jacket. Matsuyama closed with a 1-over 73 and a one-shot victory that was only close at the end, and never seriously in doubt after Xander Schauffele’s late charge ended with a triple bogey on the par-3 16th.
