Lydia Ko has finished her opening round of the Tokyo Olympics' women's golf tournament with a one-under 70 at Kasumigaseki Country Club.
Five years after claiming silver at the Rio de Janeiro 2016 - golf's Olympics introduction - Ko is looking to go one better and win New Zealand's seventh gold medal in Tokyo.
Ko sits in a seven-way tie for 16th position after her first round, four shots behind the leader.
Starting on the front nine, Ko began the first round with seven consecutive pars, before bagging back-to-back birdies in the seventh and eighth holes.
That had the Kiwi as high as third on the leaderboard - one shot back from playing partner, Inbee Park of South Korea.
Ko finished her front nine with another par, and added one more on the 10th to start her back nine.
But on the 11th, the Kiwi slipped from being in contention to as far down the leaderboard as 21st, with a double bogey, dropping two shots and falling back to an even par from her round.
Another birdie on the 14th hole took Ko back to one-under, before the Kiwi finished with four consecutive pars.
All up, Ko finished her first round with three birdies, 14 pars, and one double bogey.
"There were some goods and there were some bads as well," Ko told Sky Sport of her first round.
"I think, when I was out of position for most parts, I was able to recover really well.
"There's a lot of golf ahead of you. Even though that's the case, you don't want to be making clumsy mistakes.
"I think for most parts, I was able to tidy that up. Hopefully I'll be able to tidy up the game a little bit better overall, just to give myself more opportunities for the next few days."
Sweden's Madelene Sagstrom leads after the first round, shooting a five-under 66 to hold a one shot advantage over USA's Nelly Korda and India's Aditi Ashok, tied for second.
Ko begins her second of four rounds at 10:30am on Thursday.
