Ricky Barnes and Scott Piercy each shot 6-under 65 on Saturday to share the third-round lead in the PGA Tour's inaugural Barbasol Championship.
Barnes and Piercy reached 13-under 200 on Grand National's Lake Course.
Piercy birdied four of the first five holes. Barnes had birdies on holes 16 and 17 and is seeking his first PGA Tour win in 202 events.
Second-round co-leaders Whee Kim and Mark Hensby were among five players a shot back. Both shot 68 in the event for players who failed to make the British Open field. Jason Gore had a 63, Will Wilcox a 65, and Emiliano Grillo a 67 to join the group at 12 under.
The 43-year-old Hensby, from Australia, surged with a 4-under performance over the final three holes, starting with an eagle on the par-5 16th.
