A trio of players, seemingly untroubled by the smoky haze enveloping the course, tied for the lead after the second round of the US$300,000 Mild Seven Kuala Lumpur Open yesterday. Australian Leith Wastle, South African Craig Kamps and Taiwan's Chou Hung-nan were out in front in the Omega Tour event at Saujana Golf and Country Club on five-under-par 139. Wastle carded a four-under-par 68, Kamps a 69 and Chou a 70. South Korean Charlie Wi is a stroke behind the leaders after firing a 73, while compatriot Choi Kyung-ju, who led after the first round with a six-under-par 66, crashed to a 76. The haze from forest fires in Indonesia made it a struggle to see the greens on the par fives and longer par fours. For the first time during the tournament, officials and spectators donned face masks to protect their health. 'I would certainly consider using a mask tomorrow, particularly if the haze is stronger. I think it would feel a bit irritating though,' said Kamps. Derek Fung of Hong Kong made the cut after adding a three-over 75 to his opening 72, and then reflected on the benefits of a new endorsement deal with a Las Vegas golf club, which will include some lessons from legendary coach Butch Harmon. China's Zhang Lianwei, hoping to build on a fine joint-sixth place finish in the European Masters a fortnight ago, made the cut in equal 19th spot on level-par 144 (71-73). Hong Kong's Dominique Boulet missed out with 151 (76-75).
