Lorena Ochoa retired Tuesday after a career in which she was the No. 1 player in women's golf the last three years.
The 28-year-old Mexican announced her decision on her website and is to elaborate on her plans Friday.
"Lorena Ochoa confirms her retirement from the LPGA, as news reports in some media have said today," her statement said. "The reasons and more details on the matter will be given by Lorena personally in a press conference on Friday in Mexico City. Lorena will share this news of a new stage in her life with her sponsors, family members and friends."
Ochoa has said she wanted to concentrate on her family and charities. She was married in December to Andres Conesa, the chief executive of Aeromexico airline. He has three children from a previous marriage.
Ochoa was set to play next week in the Tres Marias tournament in Morelia, west of Mexico City. It was not clear if she will play.
