Stacy Lewis returns this week to the scene of her first title, at the Kraft Nabisco Championship in 2011, but this time she'll pursue a major crown with the world No. 1 ranking next to her name.
Lewis said the first thing on her mind this week will be trying to win a tournament, rather than holding on to that coveted top ranking.
"There are so many things that I can't control," the Texas native said. "I can't control how Yani (Tseng) plays, how In-bee Park plays.
"If they go out and play better than me, then I lose the No. 1 ranking.
"If I go out there and take care of myself, I'll be at that No. 1 ranking."
A star-studded field will descend for the season's first major championship and will feature 111 players, all vying for $300,000 in first-place prize money from a $2 million purse at the Mission Hills Country Club course in Rancho Mirage, 10 miles (16 kilometers) southeast of Palm Springs.
South Korea's Yoo Sun-young is the defending champion at the first major championship of 2013.
Yoo may have won the title, but everyone will remember the championship as the one that compatriot Kim In-kyung lost.
Last year, on the final hole of regulation, Kim rolled her birdie putt within a foot (30 centimeters) of the hole.
Rather than marking and letting her partner finish, Kim went to tap in her par putt. But her ball did a horseshoe around the cup.
A shocked Kim finally tapped in for bogey, which dropped her into a tie for the lead with Yoo, who was already in the clubhouse.
In the playoff, both players reached the green at the par-five 18th in three.
But Kim left her birdie effort short and Yoo did not. Yoo rolled in her 12-footer for birdie and the shock victory. It was Yoo's first major title.
Kim said she was ready to move on from last year's disappointment.
"I learned a lot," said Kim. "I think last year was (a) big turning point of my life of learning and what's really important. It just gave me (a) different view of it."
However, Kim's playoff record took another hit last week after Beatriz Recari defeated Kim in a two-hole sudden death playoff at the Kia Classic.
The field this week will include 18 of the top 20 players in the world and 40 of the top 50.
The youngest player is 14-year-old Angel Yin, who was the last to get in the field after she shot a five-under 67 in qualifying on Tuesday at Mission Hills.
