Lorena Ochoa Reyes (Spanish: [loˈɾena oˈtʃoa] ⓘ; born 15 November 1981) is a Mexican former professional golfer who played on the U.S.-based LPGA Tour from 2003 to 2010.

She was the top-ranked female golfer in the world for 158 consecutive and total weeks (both are LPGA Tour records), from 23 April 2007 to her retirement on 2 May 2010, at the age of 28 years old.

An 11-year-old Ochoa approached the professional Rafael Alarcón, 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.

[12] While a student in Tucson, Ochoa received regular tutoring and greatly improved her English by watching movies and reading magazines between practice and tournaments.

[13] She was very successful in women's collegiate golf in the next two years, winning the NCAA Player of the Year Awards for 2001 and 2002, finishing runner-up at both the 2001 and 2002 NCAA National Championship[14] and being named to the National Golf Coaches Association (NGCA) 2001 All-America First team.

The Cup is given to the player who has the best scoring average versus par with at least 20 full rounds played during a season.

[14] In November 2001, Ochoa was presented with Mexico's National Sports Award by Mexican President Vicente Fox.

[14] She was the recipient of the 2003 Nancy Lopez Award, which is presented annually to the world's most outstanding female amateur golfer.

[22] In her rookie season on the LPGA Tour in 2003, she had eight top-10 finishes, including runner-up finishes at the Wegmans Rochester and Michelob Light Open at Kingsmill, ending the season as the Louise Suggs Rolex Rookie of the Year[23] and ninth on the LPGA official money list.

By the end of the year she won six tournaments, topped the money list and claimed her first LPGA Tour Player of the Year award which goes to the player who gains the most points throughout the season based on a formula in which points are awarded for top-10 finishes and are doubled at the LPGA's four major championships and at the season-ending ADT Championship.

[27] In August 2007, Ochoa won her first major championship at the historic home of golf, the Old Course at St Andrews, with a wire-to-wire win by four shots at the Women's British Open.

[29] Also in 2007, Ochoa became the first woman ever to earn more than $4,000,000 in a single season, surpassing Sörenstam's previous record of $2,863,904.

This gave her the final tournament win she needed to qualify for the World Golf Hall of Fame, although she cannot be inducted until she completes ten seasons on the LPGA Tour.

In November 2008, she became the host of a new annual LPGA event, the Lorena Ochoa Invitational, held at her original home course, Guadalajara Country Club.

The Lorena Ochoa Foundation operates La Barranca, a primary school in Guadalajara with 250 underprivileged students and an innovative curriculum.
