Mexico’s Lorena Ochoa, who retired in April 2010 as the world’s top-ranked women’s golfer, said Thursday she is convinced she will never return to the LPGA Tour.

“I’m not going to play in the LPGA. I’m sure of that,” Ochoa said at the presentation here of her book “Soñar en Grande” (Dream Big), which tells how she took up golf, her rise to the pinnacle of her profession and her retirement at age 28.
