Kerr shot a 3-under-par 69 in the final round for a one-stroke victory over Inbee Park and Angela Stanford at the Lorena Ochoa Invitational in Mexico.

The result boosts her four places to No. 11, putting her ranking points average at 6.22.
The only change in the Top 10 this week has Park edging past Choi Na-yeon for the No. 3 ranking, pushing Choi to fourth.
Yani Tseng, who took over the rankings' No. 1 spot in February 2011, has an average of 12.24, safely ahead of Stacy Lewis, whose average is 9.32. Park has an average of 8.55 and Choi comes in at 8.46.
Suzanne Pettersen is fifth with an average of 7.88, not far ahead of No. 6 Feng Shanshan (7.78). Jiyai Shin comes in seventh at 7.38. Ai Miyazato (7.03), Ryu-So-yeon (6.57) and Mika Miyazato (6.34), in order, complete the Top 10.
