PORT ELIZABETH, South Africa -- Trevor Immelman shot a course-record 9-under 63 Saturday to take a three-stroke lead into the final round of the South African Airways Open.

Overnight leader Patrik Sjoland, who set the previous course record of 64 on Friday, shot 69 and slipped to third, five shots behind Immelman's 20-under 196.

Ernie Els managed a 66 and is second to Immelman, the PGA TOUR Rookie of the Year, on the 6,963-yard, par-72 Humewood Golf Club course.

"It was a great day for me. Any time you can shoot a good round in Ernie's presence is a great feeling," Immelman said.

Els was satisfied with a round that included five birdies and an eagle.

"I hit the ball beautifully, so I can't complain. I've got to play the same in the final round and then I'll definitely have a chance," he said.

Els said that Immelman's birdies at Nos. 11 and 18, where he made bogey and par, were the difference between the two.

Retief Goosen and Andrew Raitt shot 68 and are seven shots back in a tie for fourth. Lee Westwood shot his third consecutive 68 for a share of sixth with Darren Fichardt, who had a 7-under 65.
