IRVING, Texas — David Duval gets only limited chances on the PGA Tour these days, much different from 15 years ago when he was the No. 1 player in the world.

So Duval gutted it out Thursday at the Byron Nelson Championship despite the pain from a muscle issue in his right elbow, a day after his stepson had to drive him because he couldn’t even use that arm.

“I’m just glad I chose to tee off today because I was seriously considering not,” said Duval, who almost withdrew about a half-hour before his round.

Duval, now 42 years old and ranked 890th in the world, birdied his last three holes — Nos. 7-9 — after pitching in from 57 feet for another birdie at the fifth hole. He shot 4-under-par 66, a stroke behind leader Peter Hanson and tied with Marc Leishman and Tim Wilkinson.

After a bogey on his 12th hole, the 528-yard third hole, Duval was even par for his round. He had the long pitch on No. 5, and a similar shot from 43 feet at the par-5 seventh hole started his closing birdie stretch. He sank putts of 3½ and 17 feet to finish.

Duval hasn’t led at the end of any round on the PGA Tour since the fourth of five rounds in Las Vegas in 2002. This is only his eighth tournament this season, matching last year’s total.
