Chacarra flies the flag for Spain in China Open

Australia's Jack Thompson, who started from the 10th tee, looked to have a stranglehold on the tournament midway through his second round and was six under par for the round after 13 holes and 11 under in total.

Thompson, 25, who was born in the southern city of Adelaide, then made bogey at the par four fifth hole - which once again played the most difficult of the 18 holes, and then closed with a bogey on his 17th hole and a double bogey on his final hole to finish with a two under par 70.

"I was probably rushing a bit because it was getting dark," Thompson said. "But I am playing well and looking forward to the next two days. I will learn from what happened today and come back stronger."

Thompson now stands at seven under par after two rounds, along with Ogletree and fellow American Paul Peterson, who shot three under par today.
