Lorena Ochoa (born 15 November 1981) is a Mexican professional golfer. She was an active player on the U.S.-based LPGA Tour from 2003 to 2010, and was the number one ranked female golfer in the world for over three years, from April 2007 to May 2010. As the first Mexican golfer (of either gender) to be ranked number one in the world, she is considered the best Mexican golfer of all time.
Ochoa took up golf at the age of five, won her first state event at the age of six, and her first national event at seven.
An 11-year-old Ochoa approached the professional Rafael Alarcon, 1979 winner of the Canadian Amateur Championship, as he worked on his game at Guadalajara Country Club, where her family lived near the 10th tee. She asked him if he would help her with her game. Alarcon asked her what her goal was, "She said she wanted to be the best player in the world."
