"I have been close so many times".
Bubba Watson, in search of his fourth win of the season, dropped into a tie for 13th with a final-round 2-over 72.
The 34-year-old, who emigrated to the United States from Seoul with his family at age eight, finished 72 holes at the mountain resort course in White Sulphur Springs, West Virginia, on 19-under 261. The only blemish on his card was a bogey on the par-4 11th after driving into the rough.
4 (5:45 p.m. ET): Na finishes off a 6-under 64 and a 19-under total and he will be your victor! In the playoff, Knox hit wedge from 131 yards to almost the same spot on the 18th green, and his long birdie putt curled left to right and into the cup.
Kraft (70) wound up second, while Jason Kokrak (67) and Brandt Snedeker (64) tied for third at 13 under. He began the day one shot behind co-leaders Kelly Kraft and Harold Varner III.
Na's birdie stretch included made putts of 24, 33 and 43 feet.
"It's nice to get that second trophy", said Na. "The first day the putter felt bad, and (then) it just clicked". "I see the records on TV, most starts since winning". The Rangers, mired in last place in the AL West, announced the trade Sunday prior to a game at Detroit and said corresponding moves on the 25-man roster will be made once the players report.
The top four players not already exempt among the top 12 finishers will earn spots in the British Open at Carnoustie starting July 19. Zander Lombard of South Africa and Andy Sullivan of England earned the other two spots.
For Na, who finished seventh at the 2016 U.S. Open to post his best finish in a major, the win bumped him up 40 spots to 18th in the FedExCup standings.
Gov. Justice had nothing to do with their pairing for Saturday's third round in which Watson shot 5-under 65 to climb into sixth place and Bradley's 67 move left him in 14th. He now has four top-8 finishes this season and looks poised for great success.
"Obviously, I would have loved to win after leading coming into today, but, you know, sometimes you run into a guy that makes a lot of putts", Kraft said. Since this tournament debuted in 2010, there have been four first-time champions, but no third-round leader has won. Hee Young Park won a playoff after she and Angela Stanford each finished at 258 in the Manulife Classic in Canada in 2013 (par 71), while Karen Stupples shot 258 at the Welch's/Fry's Championship in Arizona in 2004 (par 70).
The world No 65 missed from 10 feet to bogey the 11th but converted from a similar distance at the 16th, before holing a 15-footer to save par at the 17th and sealing his victory with a par at the last. He would go on to shoot a 66 and finds himself at 14 under.
Fox had an 8-foot birdie putt to extend the playoff, but it caught the lip and spun away.
"Tough to describe how incredible this feels", Knox said.
