Matthew Wolff could not duplicate the career-best form he showed in the opening round of the World Wide Technology Championship at Mayakoba on Friday, but he remains atop the leaderboard entering the weekend. 

Wolff carded a 68 in the second round to sit at 13 under par for the tournament at El Camaleon Golf Club, bogeying two of the last three holes after posting a flawless 61 Thursday. 

The 22-year-old American holds a two-stroke lead on countryman Scottie Scheffler (64), with home-crowd favourite Carlos Ortiz (65) and defending champion Viktor Hovland (65) three back at 10 under.

Sergio Garcia (69) and Justin Thomas (65) are among 10 players at nine under for the tournament. 

"It was a hard finish, but I was really happy with how I played today," Wolff said. "Felt like it was pretty difficult this afternoon, honestly. 

"Following a round like I had yesterday, it’s not always easy to come out and keep on making birdies and glad I proved to myself that I could do it. I put myself in a really good spot, so I’m excited for the week."

Further down the leaderboard, Justin Rose (70) is at five under, with Rickie Fowler (72), Charl Schwartzel (69), Patrick Reed (65) and Keegan Bradley (67) among those just making the cut at four under. 

On the wrong side of the line were Ian Poulter (73) at three under, Luke Donald (67) and Shane Lowry (69) at two under and Brooks Koepka (71) at even par.
