MIAMI (AFP) — New Zealand's Lydia Ko fired a bogey-free four-under-par 68 to seize a two-stroke lead after Saturday's third round of the LPGA season-opening Tournament of Champions.

The 26-year-old Seoul-born Kiwi stood on 12-under par 204 after 54 holes at Orlando's Lake Nona after her second bogey-free round in a row.

Ko, a member at Lake Nona, seeks her 20th career LPGA triumph and her first since the 2022 Tour Championship.

"I played really solid," Ko said. "There's still a lot of golf to be played. I'm just going to enjoy it. I'm sure there are going to be nerves, wake up a couple times overnight, but that's part of it.

"I'm going to take it all in and be excited to play one more round."

US teen Alexa Pano fired a bogey-free 67 to grab second on 206 with compatriot Ally Ewing third on 208 and Japan's Ayaka Furue, Mexico's Gaby Lopez and Scotland's Gemma Dryburgh sharing fourth on 209.

"I'm having a great time. I don't know if anyone is having more fun than me," Pano said.

"I've been playing pretty solid all week, even when I struggled today I was able to keep it together, so just staying positive, having a good time and sticking to my game plan."

World number 12 Ko, a two-time major champion, won her most recent title at last year's Saudi Ladies International on the Ladies European Tour. She also won last month's Grant Thornton Invitational mixed team event alongside Australian Jason Day.

Ko doesn't feel a great home-course advantage despite living at Lake Nona.

"There've been some situations where normally I'd think about what I need to do for the next shot, but here I've just gone up to a shot and said I think it's a 3-wood or a 5-wood," Ko said.

"I'm sure there's an advantage some parts but you still have to hit good shots. The person who plays the best golf is going to win. I'm hoping I can do that.
