Jhonattan Vegas was in front for first time in a major and didn't back down in a PGA Championship filled with drama everywhere but at the top of the leaderboard.
Looming large amid an eclectic mix of contenders is world No.1 Scottie Scheffler, still not in full control of his game but only three shots back going into the weekend.
Vegas cruised through the back nine at muggy Quail Hollow and was 10 under par until he made a mess of a bunker shot and then missed a three-foot putt on 18 and ended an otherwise splendid day with a double bogey for an even-par 70, giving him a two-shot lead.
