Bryce Molder birdied six of his last nine holes for a 6-under 64 and a one-stroke lead Thursday after the first round of the Dean & Deluca Invitational at Colonial.
Molder was in the first group of the day off the 10th tee, and was on the 16th green when play was stopped for 75 minutes because of rain and lightning. He completed his seventh of nine consecutive pars when play resumed, then had all of those birdies on the front nine.
Patrick Reed, Anirban Lahiri and Webb Simpson shot 65.
Colonial member Ryan Palmer was among four player tied for fifth at 66. Jordan Spieth, the world's No. 2 ranked player, had a 67 even after missing the first six fairways.
