MALELANE, South Africa — Michael Jonzon of Sweden had three birdies and an eagle through seven holes today en route to a 7-under 65 and a share of the lead at the Alfred Dunhill Championship.

Jonzon added two birdies on the back nine at Leopard Creek for a bogey-free opening round. He shares the lead with Len Mattiace of the United States.

"The greens were very receptive, and even though I wasn't driving that well today, it didn't matter what side of the pin you left the ball," Jonzon said. "It all went right for me."

Mattiace had one bogey and eight birdies.

"I don't think I've ever played a round where I've hit it close thaa.

"I really challenged myself" Mattiace said.

Lee Westwood, Robert Rock, Johan Edfors and Rafael Cabrero Bello each shot 66.
