Golf: Lydia Ko breaks three-year LPGA title drought with dominant win at LOTTE Championship in Hawaii

Lydia Ko's LPGA title drought is over, after a flawless four rounds in Hawaii was capped off by a seven-under par 65 - enough for a seven-shot win at the LOTTE Championship.

The former world No.1's first title in nearly three years comes hot on the heels of a second-place finish at the ANA Inspiration Major two weeks ago.

Backed up a 67,63 and 65 through the first three days, Ko entered the final round with just a one-shot lead, but the 23-year-old started solidly, sinking two birdies on the front nine, as her rivals faltered on a gusty day at the Kapolei Golf Course.

But after the turn, Ko pulled clear, dropping five birdie putts to finish clear of a pack of four chasers.

"[There are] a lot of thoughts going through my mind right now," Ko said immediately after her victory. "I know I'd played really solid golf coming up to this week.

"Sean [Foley] has, in particular, been a huge help to clear a lot of questions and doubt in my mind.

"I told my mum this morning [that] before Marathon [Classic], I couldn't even sleep on Saturday night. Even though I'd been in that position before, because it'd had been such a long time, I think I was putting a lot of pressure on myself.

"I know there were expectations, but I slept great last night. I just said, 'hey, my fate is already chosen and I'm just going to play the best golf I can today'.

"I just continued to stick to my gameplan. It proves it to myself, I think that's the biggest thing."

After such a long time between victories - more than 1000 days - Ko thought she may never win another tournament.

"When you're in that position and it doesn't happen, you do doubt. If I said no, I didn't doubt myself at all, that would be a lie.

"Hand on my heart, there were times if I wondered if I'd ever be back in the winner's circle.

"I'm obviously grateful for everything that's happened in my career so far. I believe that we're in the position that we're meant to be in.

"I've had an unbelievable and fun week here in Hawaii."

Ko held off challenges from Inbee Park, Nelly Korda, Leona Maguire and Sei Young Kim  to finish 28-under and claim her 21st career title.

The Kiwi completed a wonderful four rounds of golf, extending her bogeyless run to 100 holes through her last two tournaments.
