In-Bee Park has enjoyed her first 12 months as world No 1 and arrives in Hawaii hoping to claim her maiden LPGA Tour victory of 2014.
The 25-year-old Korean enjoyed one of the most impressive seasons in history last year when she climbed to the top of the world ranking, triumphed in three women's majors and topped the money list.
Looking back Park said: "Obviously the time has gone really fast. This was the week I took over the number one spot last year, and a lot of things happened since this week.
"I've had a lot of wins and I've experienced a lot of things. A lot of things going well for me in my career.
"I feel like I'm probably a lot more mature player than I was last year and I feel more comfortable out here and being in the number one spot feels a little more comfortable now."
This week's Lotte Championship at Kapolei, on the Hawaiian island of Oahu, has attracted a good field although defending champion Suzann Pettersen is absent.
The Norwegian, ranked second in the world, will miss her third successive event due to a nagging back injury.
As for those teeing-up, Hawaii native Michelle Wie will hope to do well on her own patch following a runner-up finish in the first major of 2014 .
Also competing is world No 4 Lydia Ko of New Zealand, making her second appearance in the tournament.
