Irving, TX (SportsNetwork.com) - Steven Bowditch fired an 8-under 62 Thursday and grabbed a 2-shot lead after the opening round of the Byron Nelson Championship
Bowditch has one PGA Tour win, which came last year at the Texas Open.
Jimmy Walker, who won the Texas Open earlier this year, is alone in second place after a 6-under 64. Ryan Palmer and James Hahn share third place at minus-5.
Keegan Bradley carded a 4-under 66 at TPC Four Seasons Las Colinas and was joined in fifth place by Tom Gillis and John Merrick. Dustin Johnson headlines a group of 13 players at minus-3.
Masters champion Jordan Spieth carded a 1-under 69 and is part of a large group tied for 33rd. Spieth started with a birdie at the first, but followed with eight straight pars.
Around the turn, Spieth played his second shot at the 10th from an awkward stance, but still dropped it inside three feet. He knocked that in for birdie. After a trio of pars, Spieth played his third at the 14th to six feet, but missed the par putt to slide to minus-1. He closed his round with four pars in a row.
Bowditch, who played in the morning wave, got off to a quick start as he poured in a 24-footer for birdie at one. After a pair of pars, he made another long birdie try, this one from 30 feet out, at the fourth.
He posted back-to-back birdies at six and seven, then made the turn at minus-5 after rolling in a 29-foot birdie effort at the ninth.
Bowditch dropped his approach inside six feet at the 12th and converted that for another birdie. After a birdie at the 14th, Bowditch got up and down for birdie from a bunker at the par-5 16th. He capped his bogey-free round with a pair of pars.
"I got off to a pretty good start. I made a couple of putts early. From there, I just sort of had some momentum," Bowditch said. "I kept hitting fairways, that's the big thing out here being so wet. You've really got to keep it in the fairways."
Walker played the back nine first and birdied the 10th from 10 feet out. He converted a birdie effort from off the green on No. 12, but gave that stroke back as he 3-putted for bogey at 14.
After four pars in a row, the five-time PGA Tour winner drained a 5-foot birdie try at the first. Walker followed that with three more pars before catching fire down the stretch.
Walker birdied the fifth to move to 3-under. He got up and down for birdie from a bunker at the par-5 seventh. Walker birdied the eighth and ninth, both from inside eight feet, to get within two of Bowditch.
"That always feels good. A good finish, got a good putt to go on the par-5 (seventh), then hit really quality iron shots on eight and nine," Walker said of his final three holes. "This was the first PGA Tour event I ever played ... so it's kind of a special place for me."
NOTES: Bowditch's 62 tied his career-low round on the PGA Tour ... Danny Lee, who is tied for eighth at minus-3, had a hole-in-one on the par-3 17th, and that was one his two eagles on the day ... Defending champion Brendon Todd stumbled to a 2-over 72 and is tied for 108th ... With wet conditions from recent rain, lift-clean-and-place rules were utilized.
