WHITE SULPHUR SPRINGS, W.Va. — Kevin Na has broken a nearly seven-year winless drought on the PGA Tour, shooting a 6-under 64 Sunday for a five-stroke victory at A Military Tribute at The Greenbrier.

Na birdied six of his first 10 holes to open up a big lead over third-round co-leader Kelly Kraft on the Old White TPC in West Virginia. The 34-year-old Na cruised from there and finished at 19-under 261.

Na's only previous tour win came in Las Vegas in October 2011.

Kraft shot 70 and finished second at 14 under. Brandt Snedeker and Jason Kokrak tied for third at 13 under. Snedeker had a 64 and Kokrak shot 67.

Kraft, Snedeker, Kokrak and Austin Cook earned their spots in the British Open in two weeks. The leading four players not already exempt from the top-12 finishers qualified.
