The Scotsman made just four pars on the way to a closing 4-under-par 69, to join Wakefield with a 72-hole total of 12-under 280. That included a birdie at the 18th and final hole of regulation.
"I felt comfortable all day" he said. "I don't remember any really bad shots. I took the advice of my manager, Chubby Chandler, and played for the middle of the greens and let other make mistakes. I didn't change that game plan all day and I feel quite proud of how I played all week."
Wakefield, a co-leader after Friday's second round, shot 3-under 70 in the final round.
Martin Erlandsson (66) and Soren Hansen (68) tied for third at 11-under 281.
