Rookie Grayson Murray, who missed the weekend cut last week in the John Deere Classic, won his first PGA TOUR title when he holed a 5-foot par putt on the final hole for a one- stroke victory.
Murray closed with a 3-under 68 to edge Chad Collins on Grand National's Lake Course. The 23-year-old finished at 21- under 263, a tournament record.
