Lydia Ko has the world number one golf ranking in her sights as she prepares to tee off in the final round of the LPGA tour's Kingsmill Championship in Virginia.

Ko tees off in half an hour tied for third place on 8 under par, but she has five shots to make up on the in-form American Lizette Salas.
