No matter who wins the WGC-Mexico on Sunday, it will likely be on eheck of a finish.
Red-hot American Justin Thomas shot a 5-under on Saturday to take a one-stroke lead a t 12-under. But the man right behind him is the No. 1 player in the world, Dustin Johnson, who also shot a 5-under to reach 11-under.
And one stroke behind him? Forty-two time PGA winner Phil Mickelson at 10-under and No. 3 Rory McIlroy, who was supposed to be taking it easy in his return from a rib injury.
And behind him? Well there’s UK legend Lee Westwood at 9-under and tied for 10th, Jordan Spieth, who is five strokes behind but seem capable of anything after shooting a tournament-low 63 on Saturday.
Thomas was at even par through the front nine, then raced to the top of the leaderboard with birdies on 10, 12, 15, and 16, and an ace on No. 13 that one-hopped into the hole.
Johnson did his damage on the front nine, with an eagle on No. 1 and birdies on 2 and 6 to reach the turn at 4-under.
McIlroy could have seized control of the lead early on, but he hit three bogeys to offset his three birdies on the front nine.
Mickelon had the same problem, with three bogeys against six birdies, including three in a row between 15 and 17.
But nobody topped Spieth, who eagled No. 1 like Johnson, then added six birdies between holes 6 and 16.
