Bad weather has postponed play until Monday at the Arnold Palmer Invitational in Florida.
Severe thunderstorms saw the final round initially suspended on Sunday before the decision was taken to resume play the next day.
Tiger Woods currently sits three shots clear at the top of the leaderboard ahead of fellow American Keegan Bradley and three others.
Woods will be crowned world number one for the first time in three years if he wins the event at the Bay Hill Club & Lodge.
Play is due to start again at 2pm UK time on Monday.
