GUADALAJARA - Cristie Kerr defends her title at this week's Lorena Ochoa Invitational, the penultimate event of the 2013 LPGA season. Kerr erased a two-stroke final round deficit to beat current world number one Park In-Bee of South Korea at Guadalajara Country Club last year. Kerr has already won one title this season, at the Kingsmill Championship in May. She said this week's event, hosted by former world number one Lorena Ochoa, is one of the tour's more restful stops and a perfect build up to the season-ending Titleholders, which features players who have earned top-three finishes during the season. "It's always a relaxing atmosphere," Kerr said of a tournament that this year features 36 players vying for a $150,000 first prize from a purse of $1 million.–AFP
