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.
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."
