Derksen, Zhang tied for Asian Open lead at halfway point

BEIJING -- Robert-Jan Derksen of the Netherlands and China's Zhang Lian-Wei both shot 3-under 69s on Friday for a share of the lead at the midway point of the Asian Open.

Derksen and Zhang had a one-stroke advantage over Northern Ireland's Ryder Cup regular Darren Clarke, who also shot a 69 in the second round of the $2.3 million jointly sanctioned European and Asian Tour event.

First-round leader Peter O'Malley of Australia (74) and England's Miles Tunnicliff (70) were another stroke back at the Tomson Shanghai Pudong Golf Club.

Derksen had five birdies and two bogeys. Zhang was the only player Friday to record a bogey-free round and holed a 25-foot birdie on the last hole to draw even.

The 42-year-old Zhang is aiming to become the first home winner of the tournament. He had previously won a European Tour event -- the Singapore Masters in 2003.

"I'm proud of the Olympics coming up in August and I'm glad to see a few Chinese players on top of the leaderboard," Zhang said. "It's nice, and compared to the past, it's a very exciting weekend coming up.

"I'm going to try my best for the gold. If I can pick up a medal on Sunday, I'll be very happy."
