Dustin Johnson putted for birdie on every hole Friday and shot a 4-under 67, leaving him bogey-free for 36 holes and two shots ahead of Rory McIlroy and Matt Kuchar going into the weekend at the Mexico Championship.

Tiger Woods got back in the game with a 65, and one shot from a fairway bunker that dazzled the gallery. He still was six shots behind.

McIlroy birdied his first two holes and quickly built a three-shot lead, only to be undone by a four-putt from the fringe at No. 9 that slowed his momentum. He had to settle for a 69. Kuchar had a 67.
