Daniel Summerhays shot a 4-under 67 on Saturday to take a two-stroke lead over Chris Stroud in the Mayakoba Golf Classic.
The 28-year-old, who won the Nationwide Tour's 2007 Nationwide Children's Hospital Invitational as an amateur for his biggest career victory, is seeking his first PGA TOUR win.
"Tomorrow, I'm just going to try and do the same things I've been doing all week," Summerhays said. "I'm going to try and hit the driver really well again. My swing feels really good, so I'm picking out good targets. I'm judging the wind correctly and I'm managing it well. ... I'm really looking forward to the opportunity tomorrow to take the lead into the final round of a PGA Tour event and see how I perform. "
Stroud had a 68. He and Summerhays are the only players with three rounds in the 60s on the Greg Norman-designed course.
