Does the Australian Open have a fifth set tie-break? French Open, Wimbledon and US Open final set rules

THE Australian Open is into its final week and Rafael Nadal is playing an epic five-setter against Stefanos Tsitsipas.

But what happens when if the score reaches 6-6 in the final set?

Here are the rules for all four grand slams.

Does the Australian Open have a fifth set tie-break?

The Australian Open DOES have a fifth set tie-break.

However, there is a twist.

In order to win the match, players must reach ten points in the tie-break rather than the usual seven.

The French Open DOES NOT have a fifth set tie-break.

Following a change of the rules at Wimbledon, Roland Garros is now the only tournament where play continues until one player wins by two clear games.

Yes. The US Open has used a tie-break to decide all five-set matches since 1970.

Like the French Open, players at Wimbledon used to keep playing until there was a winner by two clear games.

However, this rule was changed in 2019 with tie-breaks now being played when a fifth set reaches 12-12.

And this format was used in the final the same year when Novak Djokovic triumphed over Roger Federer.

Wimbledon's rule change means all four Grand Slams use a different format to decide five-set matches.
