Golf: Disappointing final day sees Ko finish six shots behind winner at HSBC Women's World Championship

Kiwi Lydia Ko's putter let her down in a disappointing final round to finish tied for seventh, six shots behind the winner at the HSBC Women's World Championship in Singapore. 

Ko started the day only three shots off the lead in a share of fifth, as she hunted her second tournament win in three weeks, but her touch around the green went missing at the big moments.

After three pars to start her round, Ko came to life with two birdies in three holes to move herself up the leaderboard. 

The first came at the par-three fourth, where she nailed a monster birdie putt to move her three behind the leaders. 

Her second of the day came at the par-four sixth, where she tapped in an easy birdie putt, after a beautiful iron shot to move her within touching distance of the lead. 

The momentum in Ko's round started to change, as she finished her front nine with three straight pars to sit three behind the leaders going into the final nine holes. 

But the putter that proved her trusty weapon when she won the Lotte Championship two weeks ago went missing for the 24-year-old.

She couldn't convert brilliant opportunities for birdie at nine, 10 and 12, as her rivals pulled away and her title hopes went up in smoke. 

The world No.7 finished with seven straight pars to end the tournament at 11-under and six shots behind Korean Hyo Joo Kim, who produced the round of the day to clinch the title.

Ko finished alongside Spaniard Carlota Ciganda, Korean In Gee Chun and Mexican Gaby Lopez in a share of seventh. 

The result sees Ko remain in second place in the LGPA's year-long race, just behind American world No.4 Nelly Korda. 

Kim shot the lights out in the final round to card an eight-under 64 and claim the title, after starting the day in eighth. 

Australian Hannah Green will wonder how the trophy eluded her, leading after 16 holes, but dropping shots on the final two holes to finish second. 

The players will now move to Thailand for the next LPGA tournament starting on Thursday as Ko looks to improve on her seventh place finish here in Singapore.
