Bill Glasson swiftly polished off his round at Shoal Creek, finishing before lunchtime and leaving the rest of the Regions Tradition field chasing.
Dan Forsman didn't catch up until about four hours later Thursday when he completed a run of four straight birdies at No. 14.
Forsman and Glasson shared the first-round lead at 6-under 66 in the Regions Tradition, the second of the Champions Tour's five major championships.
Glasson and Fulton Allem were first on the course and done by 11 a.m., finishing up in 3 hours, 21 minutes. The solo lead held up longer than that, though Glasson might not have noticed because he said he wouldn't spend the afternoon monitoring the scoreboard.
''My philosophy is I need all the birdies to make up for the impending bogeys I'm going to make,'' he said. ''So it doesn't do any good for me to watch. I just need to make as many birdies as I can.
''This course will get you, there's no doubt about it. It's about one of the best courses in the country.''
