Mpumalanga, South Africa (My Sportsbook) - Len Mattiace and Michael Jonzon both opened with rounds of seven-under-par 65 Thursday to share the first- round lead at the Alfred Dunhill Championship.

Mattiace, a two-time winner on the PGA Tour, has fallen out of the top 1,000 in the world rankings as his best finish in the last two years was a tie for 34th in a Nationwide Tour event.

Meanwhile, Jonzon is looking for his first European Tour victory since claiming the 1997 Portuguese Open.

Among the four players tied for third place is world No. 10 Lee Westwood. He carded a six-under 66 and was joined there by Johan Edfors, Robert Rock and Rafael Cabrera Bello.

Mattiace poured in three birdie chances in a four-hole stretch from the 12th. He made the turn in four-under thanks to a birdie at the 18th.

Around the turn, Mattiace birdied the first and second to make it three in a row. He moved to seven-under when he sank a birdie try on the par-four sixth at Leopard Creek Country Club.

Mattiace, who lost in a playoff to Mike Weir at the 2003 Masters, gave that shot right back as he bogeyed No. 7. He atoned for that error with a birdie on the eighth to end at minus-seven.

"I really wanted to get off to a good start," Mattiace admitted. "I played in a tournament last week in Argentina and I really didn't get off to a good start. So I wanted to go around and shoot a really low score and I really mapped it out and I stuck pretty good to what I thought I should do. I really challenged myself."

Jonzon got off to a flying start as he birdied the first and followed with an eagle on the par-five second. He climbed to five-under thanks to birdies on the fourth and sixth.

After six straight pars around the turn, Jonzon birdied the 13th and 15th, both par fives, to gain a share of the lead. He parred the final three holes to remain tied with Mattiace.

"I played really, really well, especially my shots into the green where I found my speed and the lines on the greens," said Jonzon. "It was just a day when you play really well. It's just sometimes that days like these happen. It's when you don't think about it when it does happen."

John E. Morgan and Alfredo Garcia-Heredia share seventh place at five-under- par 67. Fourteen more players, including Charl Schwartzel and Richard Sterne, are tied for ninth at minus-four.
