Cristie Kerr fought back to win the Lorena Ochoa Invitational on Sunday as Stacy Lewis locked up LPGA Player of the Year honours with a tie for fourth place.
Kerr had six birdies and three bogeys and parred the last three holes at Guadalajara Country Club to hold off fellow American Angela Stanford and overnight leader Inbee Park and win by one stroke.
Kerr's 69 gave her a four-round total of 16-under 272 for her 15th LPGA title and a first since her win at the LPGA Championship in June 2010.
Stanford carded a 68 and South Korea's Park a 72 for 273.
Lewis, the world number two who was coming off her tour-leading fourth victory of the year in Japan last week, closed with a 68 for 276, tied with Taiwan's Candie Kung, who also carded a 68.
The finish makes Lewis the first US golfer to win the points-based Player of the Year award since Beth Daniel in 1994.
Park came into the week 58 points behind Lewis in the race for the award, but would have needed to win here and at next week's season-ending Titleholders tournament to have a chance of capturing the honour.
