Paula Creamer chipped in for her third birdie at the 18th hole in as many rounds to extend her advantage in the LPGA Tournament of Champions.
The American's four-under par 68 on Saturday left her six shots ahead of compatriot Pat Hurst in Alabama.
Creamer, 21, birdied the fifth, 12th, 15th and last but was not totally happy with her round
"I didn't hit the ball as well as I did the other days. I was pulling some shots here and there," she said.
"But I'm pretty pleased with the way that I played overall.
"It's difficult when you go out there, and you have such a big lead and everyone is gunning for you. You've got to keep that momentum going."
Creamer missed the green with a wedge from 105 yards but chipped in to deny her rivals even a slight falter at the finish.
The tournament record of 21-under par, set by Mexico's world number one Lorena Ochoa of Mexico last year, is within reach for the leader.
"I know I can make a lot of birdies out here," she added. "I want to go as low as I can on Sunday."
Hurst also hit a 68 to move into second, one stroke ahead of South Korean 24-year-old rookie Jin Joo Hong.
She is two ahead of Korea's Birdie Kim, Norway's Suzann Pettersen and Sweden's Annika Sorenstam.
Ochoa also fired a 68 to share ninth on 211 at the event featuring 35 tournament winners from the past four LPGA seasons.
