Koreans Jin Young Ko and Amy Yang have the halfway lead at the HSBC Women’s World Championships at the Sentosa Golf Club in Singapore, Ko the current world number one in the female game, and four-time LPGA Tour event winner, Yang, recording the same scores over the opening two rounds of 69 and 67 to lead by one over American Megan Khang, Canada’s Brooke Henderson and Thailand’s Atthaya Thitikul.

For Ko it was her 16th consecutive round in the 60’s and continues the momentum she has been building since overtaking Nelly Korda to reclaim the number one position in the female game earlier this year. That she was able to do so despite visiting the water on two occasions in round one is further testament to just how well she is playing at present.

First round leader Patty Tavatanakit of Thailand was unable to build on her opening round of 67 and slipped to a round of 1 over and is back in a share of 15th place.

Su Oh heads the Australasians in 10th place at 5 under and three from the lead, Minjee Lee is at 4 under in a share of 15th place, Lydia Ko is 27th at 2 under, Hannah Green improved from her slow start yesterday with a round of 69 to be 36th and Sarah Kemp 49th in a field where this is no halfway cut.
