Bryson DeChambeau kept making so many birdies in the Mexico Championship that when he rolled in his ninth one from 45 feet, all he could do was throw his hands in the air in pure wonder.
He wasn't alone Friday in making birdies, although Rory McIlroy would like to have joined the party.
DeChambeau made seven birdies in an eight-hole stretch at Chapultepec Golf Club for an 8-under 63, giving him a one-shot lead over Erik van Rooyen of South Africa and Patrick Reed at the halfway point of this World Golf Championship. DeChambeau was at 11-under 131.
