Koepka, DeChambeau Share Masters Lead

Brooks Koepka and Bryson DeChambeau each shot a 6-under 66 and are tied for the first-round lead at the Masters in Augusta, Georgia.

Koepka and DeChambeau followed a similar path Thursday, making the turn at 1-under before scorching the back nine of Augusta National.

Koepka played a bogey-free round, making birdies on five out of six holes on Nos. 10, 12, 13, 14 and 15.

He had a chance to move to 7-under on 18, but his putt curved just right of the hole.

DeChambeau ended his round with six birdies on the final seven holes. His only misstep was a bogey on No. 14.

Phil Mickelson shot a 67 and is one shot behind the leaders.

Ian Poulter and Dustin Johnson shot 68's to finish two shots back.

Four-time Masters champion Tiger Woods finished his opening round with a 2-under 70.

Canadian Corey Conners also finished at 2-under while Mike Weir of Brights Grove, Ont., the 2003 Masters champion, shot a 72.
