McKINNEY, Texas — K.H. Lee was more than happy to play through a steady downpour in the final round of the AT&T Byron Nelson, and didn’t mind waiting out a weather delay of more than two hours Sunday.

The reward was the final spot next week in the PGA Championship.

Lee earned his first PGA Tour victory and the chance to compete on the Ocean Course at Kiawah Island in South Carolina, becoming the second consecutive Nelson winner from South Korea by finishing at 25 under, three ahead of third-round leader Sam Burns.

Heavy rain fell most of the back nine for the leaders, with puddles showing up on greens over the final holes and one ball in the fairway stuck in the middle of a fast-moving stream. The players slogged through the deluge before lightning forced a delay.

Most of the standing water was gone when play resumed two hours and 23 minutes later. Lee missed a par putt on No. 16 to cut his lead to two, but answered with two birdies. The sun came out just as Lee was finishing his 6-under 66.

Burns struggled to a 71 to finish at 22 under, a shot ahead of Charl Schwartzel, Daniel Berger, Patton Kizzire and Scott Stallings.

When the delay hit, Jordan Spieth already knew he was going to fall short again in his hometown event, played on its third course in the past four Nelsons at the rain-soaked TPC Craig Ranch in McKinney, about 30 miles north of Dallas.

Spieth, three back to start the day, shot 71 and tied for ninth, giving him his first top 10 at the Nelson since he contended as a 16-year-old in 2010 when the course was at its home of more than 30 years at the TPC Four Seasons.

South Korea’s Sung Kang was the defending champion after winning in 2019, when the second of just two Nelsons was played at Trinity Forest, a treeless links course in Dallas. The move was unpopular with fans and players, and Craig Ranch became the home following last year’s COVID-19 cancellation.

One thing about this Nelson was the same, though: notorious spring weather in Texas.

Threesomes started from the first and 10th tees just after daybreak to try to beat a forecast calling for increasing rain throughout the day.

Steady rain for two-plus hours got progressively worse as players began ducking for cover under umbrellas immediately after shots and constantly wiped grips with towels. From the start of the round, they got to lift, clean and place their shots in the fairways.

Lee, 29, went ahead for good with a birdie on the par-4 third hole and stretched the margin to four at No. 8 by putting his second shot within 4 feet for birdie. Burns threw his ball in disgust after missing a 5-foot birdie try.

Lee will get his third shot at a major after twice missing the cut at the U.S. Open. The first was in 2014, more than three years before his second PGA Tour appearance.

CHAMPIONS TOUR: Monday qualifier Dicky Pride won the Mitsubishi Electric Classic in Duluth, Georgia, for his first PGA Tour Champions title, closing with a 5-under 67 for a three-stroke victory.

Making his 11th senior start, the 51-year-old Pride had six birdies in an 11-hole stretch before dropping a stroke on the par-4 15th. He parred the final three.

Stephen Ames and Kirk Triplett each shot 70 to tie for second with second-round leader Paul Goydos (72). Brett Quigley (68), Doug Barron (69) and Billy Andrade (72) were another stroke back.

Pride finished at 11-under 205 at TPC Sugarloaf, a week after contending in the major Regions Tradition in his home state of Alabama. He won the 1994 St. Jude Classic for his lone PGA Tour victory.
