Tokyo Olympics: Lydia Ko can't capitalise on birdie blitz in mixed second round of women's golf tournament

Lydia Ko has managed to keep herself in with an outside chance of a medal at the Tokyo Olympics' women's golf, with a mixed third round at Kasumigaseki Country Club.

The Kiwi recorded a second round score of four-under, but will be wondering what could have been, after carding seven birdies along with three bogeys.

Beginning her second round at one-under, Ko was in trouble early with a bogey on the first hole, dropping her back to an even par for the tournament.

But the Rio de Janeiro silver medallist bounced back in some style, unleashing a barrage of birdies to rocket into contention.

After making par on the second, Ko went on a run of six birdies in seven holes to finish her front nine, as her score progressed from even par to six under at the halfway point of her round.

Another birdie, on the 10th hole, had Ko in the mix before six straight pars saw the Kiwi fail to make up more ground on the leading group.

But in an anti-climactic end to her second round, Ko dropped two shots on her last two holes, finishing with bogeys on the 17th and 18th.

That finish had Ko leave the course at four-under for the round, and five-under overall, making up seven places after sitting 16th after her opening round on Wednesday.

Ko trails the leader, Nelly Korda of the USA, by eight shots, after her stunning round of nine-under had her at 13-under.

The women's golf tournament still has two rounds to play, although that could be shortened to three as inclement weather threatens to disrupt the final day's play on Saturday (NZ time).
