"Im still on Cloud 9," said the 25-year-old Rosales, whose flawless final round 65 netted her a one-stroke victory in Georgia that snapped a five-year title drought on the tour. "I am just pretty happy. I have won already and that was my goal, you know to get it as soon as possible and just give confidence to myself."
But she is expected to have her hands full against a field teeming with talent, led by worlds No. 1 Annika Sorestam, Korean ace Se Ri Pak, defending champion Grace Park, who won the first major this year, and teenagers Aree Song and Michelle Wie.
Meanwhile, the 14-year-old Wie is hoping to dish out a solid performance with a new caddie in Mike "Fluff" Cowan, best known for carrying the clubs of Tiger Woods.
"This is going to be a really fun week with Fluff on my bag," said Wie, who is playing here on a sponsors exemption.
Wie missed the cut in the PGA Tours Sony Open by a shot in January and finished fourth in the Nabisco Championship.
