Darren Fichardt, David Dixon and Peter Fowler share third place at 6-under. Fichardt has completed six holes, while Dixon and Fowler are through four.
Play was originally delayed on Thursday due to high winds and they have been trying to play catch up ever since. Third-round action will restart early Sunday morning with the fourth round scheduled to begin shortly after the third round is completed.
