Australian Open is in full flow, with some of the world’s best competing against each other.
Roger Federer, Novak Djokovic and Rafael Nadal are among those still involved in the men’s singles competition.
But what happens if matches reach 6-6 in the final set?
Does Australian Open have a fifth set tie-break?
After long final sets in Grand Slam matches, the Australian Open joined Wimbledon and US Open in introducing a tie-break.
Yet, they play a different version to the others.
When players reach 6-6, they compete in a tie-break of first to ten points.
How do fifth sets work at other grand slams?
For the first time ever, each grand slam in 2019 has a different method of deciding a fifth set.
At Wimbledon, a tie-break is only used when the score reaches 12-12.
The US Open has had a fifth set tie-break played under the regular format ever since 1970, while in the French Open players are still required to play out the set until there is a winner by two clear games.
