American Jason Bohn has propelled himself into the outright lead ahead of the final day at the OHL Classic at Mayakoba.
The 41-year-old fired built on solid displays on the first two days by shooting a four-under par third round of 67 to move into first place on 15 under.
Compatriot Shawn Stefani trails Bohn by one shot following his three-under round of 68 in Mexico.
Charley Hoffman and Alex Cejka are also well positioned on 12 under, while Andres Gonzales recorded the round of the day with a five-under performance of 66 to leave him at 11-under.
Michael Putnam, who led the competition going into day three, had a nightmare round as dropped six shots with a round of 77.
