Australian fans could be watching the drama of the Masters final round late on Sunday night with thunderstorms raising the possibility of a rare rescheduling of tee times at Augusta National.
With thunderstorms forecast throughout Sunday, it has been suggested that Masters officials could make the rare move of sending competitors out in threesomes from the first and 10th tees.
With a storm expected to hit the Augusta, Georgia area around 4pm local time on Sunday, it has been rumoured final round tee times could start from 7.30am - which would be 9.30pm AEST - in order to finish the final day before it hits.
Australian fans are accustomed to the final group tee off on Sunday at the Masters at 5am AEST.
The move would be unusual given Augusta National is a strict follower of tradition and would likely prefer to have competitors tee off the first hole only, in twosomes.
Masters host broadcaster CBS would also need to be consulted, given it is one of their highest-rating sports spectacles.
The back nine of the final round at the Masters is known for its drama and finishes in a prime time TV slot on Sunday night.
But the thunderstorms have increased the possibility of an unwanted Monday finish, which has only happened four times in 82 previous Masters - the last coming in 1983.
The Masters has used two-tee starts five times, including the first three rounds in 2005 when Tiger Woods went on to victory in a sudden-death play-off on Sunday over Chris DiMarco.
