Mexican golfer Lorena Ochoa said retiring from the LPGA tour in April 2010 was an easy decision because golf was no longer a priority in her life.

"I retired gladly. I wanted to start a family, I had achieved my goals, because I no longer had the desire and the energy to get up every day (to practice)," Ochoa said during the presentation on Monday of her autobiography, "Soñar en grande" (Dreaming Big), in the western Mexican city of Guadalajara.

Ochoa announced her retirement more than two years ago to focus on her personal life, but she still plays in some tournaments, such as the LPGA's Lorena Ochoa Invitational, which starts on Thursday in Mexico.

The 30-year-old Ochoa said an injury, image problems or sponsorship problems might have made the decision to call it quits more difficult because she wanted to leave as world No. 1, a spot she held until her retirement.

The book allows the public to understand her determination on the links and tells how she spent her last day in a tournament with tears in her eyes, Ochoa said. EFE
