WGC-Mexico Championship: Leaderboard, Tee Times, and How to Watch Final Round on Sunday

Justin Thomas will begin the final round of the WGC-Mexico Championship on Sunday with a one-shot lead over Patrick Reed and South Africa's Erik van Rooyen.

Throughout the first three rounds at the Club de Golf Chapultepec in Naucalpan, just outside Mexico City, the 2017 PGA Championship winner has been the picture of consistency.

On Saturday, he shot a 6-under-par 65 to follow the scores of 67 and 66 Thomas carded in the previous two rounds respectively. Thomas bogeyed the first and last hole but offset them with eight birdies, five of which came on the back nine.

The 26-year-old finished ninth in the same event last year and is in pole position to claim a third win in nine starts this season, but he's well aware nothing comes easy at Chapultepec.

"I've been close a couple of times," he said after his third round. "I definitely feel like I have a little bit of unfinished business here. There's a lot of great players that are going to be breathing down Patrick and I and everybody's necks. I know I need to play well tomorrow. But I know I want it."

Thomas will play alongside Reed and Van Rooyen in the final round, with the trio teeing off from the first tee at 2:30 p.m. EST.

Reed would have been level with Thomas in the clubhouse, had it not been for a bogeyed at the 18th. The 2018 Masters winner finished with a 4-under-par 67 on Saturday, which was matched by Van Rooyen.

The South African had forced himself into the picture after matching the course record with a stunning 62 on Friday, which was bettered by Jon Rahm on Saturday.

Unfazed by starting the third round 10 shots adrift of the leader, the world No. 3 made six birdies in the first seven holes toward a fantastic round of 61, which was both a new course record and his best performance in a single round since turning professional.

"I think a lot of us like to talk sometimes about how unlucky we get, and today was one of those days where I got fortunate," Rahm, who hit a hole-in-one at the 17th, told reporters. "I hit the right shots, I got the right bounces and I took advantage.

The performance left Rahm four shots behind Thomas and the Spaniard will begin the final round in the penultimate group alongside Rory McIlroy and Bryson DeChambeau, who are also four shots adrift of the lead.

The world No. 1 shot 68 but missed a six-foot par putt at the 14th, while DeChambeau began the third round as the leader but couldn't quite match the 63 he carded on Friday and recorded an even par 71 on Saturday.

At 10-under, the English duo of Tyrrell Hatton and Paul Casey are also firmly in contention, while Gary Woodland and Adam Scott begin the final round at 9-under.
