Dustin Johnson added a 4-under-par 67 to his opening-round 64 and is all alone atop the board in the WGC-Mexico Championship at 11-under-par 131. He enjoys a two-stroke edge over Rory McIlroy (63-70-133) and Matt Kuchar (66-67-133).

    Tiger Woods came out of the doldrums after his Thursday 71 and posted a 5-under 66 to move up to a tie for eighth at 5 under. He made six birdies and one bogey.

    Brooks Koepka's 73-70-143, 1 over, is tied for 35th, while Billy Horschel dropped into a tie for 39th with 68-76-144, 2 over. Phil Mickelson also rebounded with a 6-under 65 after his disastrous opening 79 and is tied for 39th at 2 over.
