DeChambeau leads by one as birdies abound at WGC Mexico Championship

Bryson DeChambeau put on a putting clinic on the way to an eight-under par 63 and a one-shot lead in the WGC Mexico Championship over Erik van Rooyen and Patrick Reed.

America's DeChambeau rolled in 143 feet of putts as he built a 36-hole total of 11-under par 131 at Club de Golf Chapultepec.

Former Masters champion Reed was also red-hot on the greens on the way to a 63 that put him at 10-under alongside South Africa's van Rooyen -- who had nine birdies without a bogey in a 62 on his 30th birthday.

World number one Rory McIlroy came alive late on the way to a two-under par 69 that put him two off the lead alongside Japan's Hideki Matsuyama and American Justin Thomas.

Matsuyama was 11-under for the tournament after posting nine birdies in his first 15 holes, but two late bogeys saw him sign for a seven-under par 64.

Thomas was atop the leaderboard at 10-under after his eagle at his 10th hole of the day -- the first -- but eventually signed for a 66.
