SINGAPORE (Reuters) - South Koreans Amy Yang and Ko Jin-young were tied for the lead at the halfway stage of the HSBC Women's World Championship on Friday after carding five-under 67s in the second round, while overnight leader Patty Tavatanakit endured a difficult day.

Yang, who was tied for fifth place after the opening day at the Sentosa Golf Club, got off to a disappointing start with a bogey on the third hole but she responded with four birdies in the next six.
