Chris Kirk's Viking Classic win makes him the fifth rookie to win on the PGA TOUR this year, joining the group of Jhonnatan Vegas, Charl Schwartzel, Brendan Steele and Keegan Bradley.
Kirk's final-round 66 at Annandale included two late birdies on No. 15 and 17 that helped him move a shot past Tom Pernice Jr. and George McNeill, who finished at 21 under.
Kirk earned his TOUR card by finishing second on the Nationwide Tour money list last year. He had the lead entering Round 4, but did not pull away from the field until the final hole. Pernice and McNeill shot 67 and 68 respectively, and held the lead or a share of the lead for a majority of the back nine.
Kirk approached Annandale's finishing par-5 with a one shot lead and played it in winner's fashion -- fairway, layup, green and two putts.
It was a stellar performance that many could see coming from the former University of Georgia standout. Kirk finished second to Phil Mickelson at the Shell Houston Open in April. He also fired a third-round 63 at the AT&T National two weeks ago that eventually led to a tie for eighth.
Kirk earned 250 FedExCup points with the win, and is now No. 25 in the FedExCup Standings.
