Wilson's total, 13-under 197, led Chinese Taipei's Lin Wen-tang (64). His 65 followed successive 4-under 66 totals Thursday and Friday.

Wilson was part of a four-way deadlock at the top of the leader board when the round started, and he had to compose himself after a bogey at Saturday's first hole.

Later, he compiled three birdies in a four-hole stretch to begin the back nine, and added a birdie at the 17th hole, which gave him the lead outright.

"I am very happy with today," he said, (but) it will take a good round tomorrow. I'll just keep doing what I am doing and hopefully it will be enough."

Germany's Bernhard Langer (63) is third at 11-under 199 with four others one shot further back.
