MOUNT PLEASANT, S.C. — Lorena Ochoa has withdrawn from this week's Ginn Tribute Hosted by Annika.

The world's No. 1-ranked woman golfer said in a statement that her uncle was ill, and she needed to be with her family. Tournament organizers say she left for Mexico last night.

Ochoa has won six times this season. She finished second at the Ginn Tribute last year, losing a playoff to Nicole Castrale.
