Hong Kong’s top golfer Tiffany Chan Tsz-ching is on course for her best LPGA Tour result after shooting an emphatic 8-under-par 64 on day one of the Thornberry Creek LPGA Classic in Wisconsin, USA on Thursday. The 25-year-old, who has hit on some of her best form as a professional in the past few weeks, signed for a faultless opening with eight birdies on her way to her best round as a professional. Her day one showing was good enough for a share of fourth place at the notoriously low-scoring US$2 million Green Bay event, but Chan admitted later that she will need to maintain her solid form over the 72 holes to stand any chance of taking a first Tour title. “Coming to the course that you know there is a lot of birdie opportunities out there, you just know you have to make birdies in order to be up there or even to make the cut,” Chan told Green Bay Press Gazette . “So when it comes to easier courses, it’s actually tougher because if you can do it, everyone can do it. You have to make every shot one shot at a time and just try to make more birdies out there.” Last year, South Korean Kim Sey-young claimed the title after finishing an astonishing 31-under-par to claim victory by nine strokes. China’s Liu Yu leads the way in Wisconsin this week on 10-under-par, with two players, Yealimi Noh of the US and Jeongeun Lee of South Korea tied for second spot on 9-under-par. Chan shares fourth place with six other players, including 2012 LPGA Championship winner Feng Shanshan of China. Women’s PGA Championship: agony for Tiffany Chan as Hong Kong star misses cut by one shot Chan’s solid start in Wisconsin comes on the heels of her best finish as a professional at the end of June when she claimed a share of 13th place – and US$29,000 in prize money – at the Walmart NW Arkansas Championship. Chan has endured a chastening second year on the elite LPGA Tour, missing seven of 12 cuts, but the upturn in her form will go a long way to securing her place on Tour for next season.
