Derek Fathauer shot his second consecutive 66 Saturday to take the lead in the OHL Classic at Mayakoba. Here's how things stand after 54 holes at the Mexican resort, where Fathauer leads veteran Jason Bohn by one shot.
The leaderboard: Derek Fathauer (-16), Jason Bohn (-15), Russell Knox (-13), Justin Leonard (-13), Harold Varner III (-13), Graeme McDowell (-13)
What it means: The leaderboard is an interesting mix of youth and experience. Fathauer, 29, is looking for his first PGA Tour win. Bohn, 42, was tied for the lead until he bogeyed the 18th hole when his approach ran through the green and he lipped out his par putt. Also in the mix is 43-year-old Leonard, who earned the last of his 12 Tour wins in 2008; Scotsman Russell Knox, who is coming off a win in the WGC-HSBC Champions; veteran Graeme McDowell, who has struggled throughout 2015, and rookie Harold Varner III.
Round of the day: On a day when 46 players broke 70, Freddie Jacobson's bogey-free, 8-under 63 was the low score. He came out of the gate with four straight birdies and five in his first six holes, made a sixth on the front nine to shoot 30, then made only two on the back.
Best of the rest: Dawie van der Walt was just a stroke off Jacobson's performance, with an eight-birdie, one-bogey round of 64. Van der Walt bogeyed the second hole, but didn't drop another shot the rest of the way.
Biggest disappointment: McDowell's 1-under 70 was far from the worst round of the day, but it was the highest score posted by the top 20 players on the 54-hole leaderboard. That had to be hugely disappointing, considering that McDowell was the 36-hole leader and has struggled all year, especially on the weekends.
Main storyline heading into Sunday: It's a tossup between whether Fathauer can get his first PGA Tour win or whether McDowell can break his drought (the 2010 U.S. Open winner hasn't won on the PGA Tour since April 2013). Fathauer, winner of the 2014 Web.com Tour Championship, has a best PGA Tour finish of seventh, in the 2015 Barracuda Championship. If he does break through, he would be the sixth consecutive first-time winner this season.
