Jordan Spieth carded a 5-under 65 that even included a few wayward shots to take the third-round lead on Saturday at Colonial.
The second-ranked American was alone in the lead at the Dean & Deluca Invitational after three birdies and a huge par save in a four-hole stretch in the middle of his round.
At 12-under 198, he was one stroke ahead of Colonial member Ryan Palmer and Webb Simpson.
Palmer overcame consecutive bogeys early to shoot 66. Simpson ended with a 67 after his 3-foot par putt at the 18th hole for a share of the lead lipped out of the cup.
None of Spieth's seven PGA Tour victories have come in his home state of Texas.
Spieth hit only three of 14 fairways and 11 of 18 greens in regulation, but he hung in there with his only bogey on the last hole.
Harris English, Kyle Reifers and Martin Piller all sit two shots off the lead, while 2013 US PGA Championship winner Jason Dufner is three off in seventh place.
Overnight leader Bryce Molder faltered after following up bogeys on two of his final three holes in completing his second round with a level par 70 on Saturday.
The 37-year-old from Arkansas, whose only PGA Tour win came when he defeated Briny Baird to lift the Frys.com Open in 2011, was out in 29 and 30 on the front nine in his first two rounds but he could not produce any more magic as he began his third.
For the second time in a day, he dropped shots at the 16th and 18th and is now in a tie for ninth, five shots adrift of Spieth.
Matt Kuchar also lies on seven under after his 63, the best round of the day, saw him surge up the leaderboard.
