Cao has confidence in 'secret' strategy

GUILIN, Guangxi - China's Cao Yi hopes a "secret" strategy can help him rediscover his winning form at this week's 1.5 million yuan ($235,000) Guilin Championship.

The fifth event on this year's PGA Tour Series-China marks the first professional golf tournament in Guangxi Zhuang autonomous region.

The 27-year-old Cao is fourth on the Tour's order of merit due in large part to his playoff victory over England's William Harrold at the Chongqing Championship in March, but has otherwise had an inconsistent season.
