Matthew Wolff is back to his exciting best on the PGA Tour and he shot a 68 on day two of the World Wide Technology Championship to take a two-shot lead.
Wolff, who fired a round of 10-under-par on Thursday, followed up this score at El Camaleon Golf Club on Friday with four birdies and one bogey on the front nine.
The 22-year-old made two birdies and two bogeys on the back nine, including one on the 18th hole, to shoot 3-under-par. He leads by two ahead of Scottie Scheffler on 13-under-par.
"I'm just happy, I'm blessed to be out here. It's not easy and there's a lot of ups and downs... That's something I'm learning as I'm getting older and being out here," Wolff said earlier this week.
Last season, the young American opened up to the golfing public about his struggles with mental health which resulted in a short break between the Zurich Classic of New Orleans and the US Open.
He has the edge over Scheffler with two rounds left but Scheffler will be determined to earn his long-awaited maiden PGA Tour victory.
The 25-year-old was sublime on his Ryder Cup debut last month, most notably beating the World No. 1 Jon Rahm in the Sunday singles and he was sublime once more on Friday in Mexico.
Scheffler fired a bogey-free round of 7-under-par to reach 11-under-par. The closest he has come to a PGA Tour victory was when he lost in the final of last season's Dell Technologies Match Play.
Viktor Hovland is in a promising position to become the first person to successfully defend the World Wide Technology Championship, or the Mayakoba Golf Classic as it used to be called.
He shot a second-round score of 65 to reach 10-under-par and three shots behind Wolff. Home favourite Carlos Ortiz is also in tied third place on 10-under-par.
Sergio Garcia, Billy Horschel and Justin Thomas are a further shot back on 9-under-par and four shots behind Wolff heading into the weekend.
