From the AP report:
Schwartzel (74) finished terribly, making two bogeys and a double-bogey in his last five holes to fall back to 11-under and allow Sullivan (67) a chance at victory in the playoff.
Both players missed the fairway off the tee in the playoff, but Sullivan sent a low pitch from under a tree onto the green, and then holed out for an unexpected birdie to win.
"It's unbelievable," Sullivan said. "After Saturday I didn't think I stood much of a chance with Charl getting ahead that far."Hideki Matsuyama and Jimmy Walker are tied for the lead at 17 under heading into the final round of the Hyundai Tournament of Champions at the Plantation Course in Kapalua, Hawaii.
