GUADALAJARA, Mexico -- Lexi Thompson moved into position for her second victory in her last four starts, taking the third-round lead Saturday in the Lorena Ochoa Invitational.
The 18-year-old Thompson shot a 5-under 67 to reach 13-under 203 at Guadalajara Country Club. She had a one-stroke lead over South Korea's I.K. Kim.
Thompson won the 2011 LPGA Navistar Classic at 16, and took the LPGA Malaysia last month for her second tour title. After opening with a 72, she had a 64 -- the best round of the week in the 36-player event -- Friday to pull within a stroke of second-round leaders Anna Nordqvist, So Yeon Ryu and Pornanong Phatlum.
Kim birdied the final two holes for a 67.
Third-ranked Stacy Lewis was third at 11 under after a 67.
Ryu was another stroke back after a 71. Nordqvist and Phatlum each shot 72 to remain 9 under.
Tournament host Lorena Ochoa won 27 LPGA Tour titles before retiring in 2010.
