They are world No.52 Pornanong Phatlum, Moriya Jutanugarn, Thidapa Suwannapura and Nontaya Srisawang.
Pornanong will be looking forward to her first weekend rounds at the major after missing the cut in her previous two appearances.
However, she said yesterday it would be tough for her to beat the course.
"The lay-out is challenging with many bunkers. The greens are big but have a lot of slopes," she said.
Having taken a four-week break, Pornanong, who is 21st on the LPGA money list, will tee off with Spain's Belen Mozo and South Africa's Ashleigh Simon in the first two rounds.
LPGA rookie Thidapa said that it was a great feeling to be at the Home of Golf with her target being making the cut.
She is in the same group with Malene Jorgensen of Sweden and Italy's Giulia Sergas.
Moriya, another LPGA rookie, is grouped with Lee Il Hee of South Korea and Carline Masson of Spain. Ladies European Tour member Nontaya will play alongside Marianne Skarpnord of Norway and amateur Gabriella Cowley of England.
World No.19 Ariya Jutanugarn was forced to withdraw from the event due to injury.
