For the second day in a row, Keegan Bradley bogeyed Nos. 1 and 18 at the Byron Nelson Championship in Irving, Texas.
Unlike the first round, Bradley didn’t set a course record, but he still finished with a three-stroke lead.
Bradley started and ended his round Friday with those bogeys, part of a 1-under-par 69 that got him to 11-under 129, the lowest 36-hole total at the Nelson since 2001.
‘‘I'm almost more proud of this round than yesterday because I didn’t feel comfortable all day,’’ said Bradley, whose opening 60 included his only bogeys at those same holes in the middle of that round.
Tom Gillis, who shot 63 in the first group of the day off the No. 10 tee, and Sang-Moon Bae (66) were tied for second.
A stroke back were John Huh (64), Ryan Palmer (68), and 2011 Masters champion Charl Schwartzel (70). Schwartzel had an opening 63 and was the closest to Bradley after the first round.
Bradley, whose first PGA Tour victory came as a rookie at the Nelson two years ago, started his second round with a drive that missed the fairway at the 458-yard first hole, then left his approach short of the green.
‘‘The first hole is probably the easiest hole out here,’’ he said. ‘‘I don’t know why I keep making bogey on that hole.’’
At No. 18, he drove right into rough under the trees near a cart path. He punched the ball, which rolled and flirted with water to the left before settling into a swale behind the green. He chipped to 6½ feet, but missed the par putt.
Defending champion Jason Dufner, playing with Bradley, had his second consecutive 70.
Guan Tianlang, the 14-year-old amateur from China, had a tough day with a 7-over 77. After an opening 70, Guan missed the cut at 7-over 144.
Two-time heart transplant recipient Erik Compton matched Gillis for the best round Friday, his 63 a nine-stroke improvement from the opening round to put him in a tie for 13th.
World Match Play — Ian Poulter bogeyed the last hole and lost to Thomas Aiken, 1 up, and was thereby eliminated with his second loss in round-robin play in Kavarna, Bulgaria.
‘‘I have no excuses,’’ Poulter said. ‘‘There is no excuse for that display of golf over the last two days. It’s disgusting, disgraceful, and there’s no explanation. I should have been able to finish the match off.’’
Poulter lost to Thongchai Jaidee on Thursday. On Friday morning, Jaidee beat Aiken, 1 up.
Jaidee is one of only four players to win both early matches, joining Francesco Molinari, Gonzalo Fernandez-Castano, and Scott Jamieson.
Richard Sterne also ensured his advancement by defeating former US Open champion Geoff Ogilvy, 5 and 4, while defending champion Nicolas Colsaerts recovered from his first-round loss, beating Kiradeck Aphibarnrat, 3 and 2.
LPGA — Jessica Korda had her second straight bogey-free round, shooting a 7-under 65 to take a one-stroke lead over Karrie Webb after the second round of the Mobile Bay (Ala.) Classic.
Korda, 20, had seven birdies to reach 13 under. Webb, 38, also had a bogey-free round, birdieing the last three holes for a 63.
Chella Choi was two strokes back at 11 under after a 66.
Sydnee Michaels had a course-record 62 to join Pornanong Phatlum (65) and Thidapa Suwannapura (67) at 10 under.
Michelle Wie missed the cut with rounds of 74 and 75. Brittany Lincicome also missed the cut, shooting 75-70.
European — Scotland’s Craig Lee took a one-stroke lead over Peter Uihlein of Mattapoisett, Mass., and Chile’s Mark Tullo during the suspended second round of the Madeira Islands Open.
Lee shot a 4-under 68 to reach 9-under 135. Uihlein settled for a 64 after playing the first 12 holes in 10 under with an eagle and eight birdies. He bogeyed Nos. 15 and 16.
