2026 Australian Open

The Australian Open gets underway on Sunday 19th of January where Jannik Sinner will be once again looking to defend his title on the men's side having won his second consecutive Australian Open in straight sets against Alexander Zverev. He will be looking to become only the second player during the open era (Novak Djokovic) to win three on the bounce.

On the women's side of the tournament, American Madison Keys ended Aryna Sabalenka's quest for three on the spin by defeating her in three sets and becoming the first American winner since Sofia Kenin (2020).

The long wait continues to see an Australian in the men's final, 2005 when Lleyton Hewitt was defeated is still the last time that happened! On the women's side, Ashleigh Barty's win in 2022 is much more recent!

In this blog we will be looking at some statistics for the tournament, we also have a 2026 Australian Open Preview blog packed full of information which you will find useful.

Early Rounds Favs vs Dogs

How often does an underdog win in the early rounds of the Australian Open?

It's roughly 1 in 4 underdogs win in the first round of the Australian Open although there are more on the women's side than there is on the men's side.

  • Men's 1st Round Underdog: 139-613 (22.68%)
  • Women's 1st Round Underdog: 175-630 (27.78%)

The figures remain consistent through both the second and third rounds too with the underdogs still around the 1 in 4 wins, overall from 2,185 completed matches covering the first three rounds for both ATP and WTA, the underdog has been successful 25.54% of the time (558).

Later Rounds Favs vs Dogs

When does the underdog record improve during the Australian Open?

As you would expect, the matches get more closely matched as the tournament advances into the latter stages. In round four on the women's side, the underdogs win percentage rises above 30% for the first time (31.65%) and then goes to 33% for the quarter-finals.

Things are not so clear on the men's side, whilst round four does have a higher underdog win rate (25.33%) than the previous three rounds and it does drop again for the quarter-finals (24.32%) and the semi-final is another matter with just 5.56% of underdogs being successful!

Australian Open Correct Set Betting

What is the most common winning set score at the Australian Open?

This will differ on both sides with the men's being best of five and the women's being best of three and there does seem to be more clearcut matches on the women's side.

A 2-0 win over the last ten years has occurred in 69.01% of the matches (864) whilst a 2-1 win has made up the other 30.99% of the matches (388). The opening two rounds both see 69%+ of games finish 2-0 whilst that drops to 63% in R3 and then 61% in R4.

On the men's side, a whitewash happens much less often with just 45.87% (561) of the wins being 3-0 with the R3 matches having the biggest percentage of matches finishing 3-0 with 51.28% of them.

The other matches have seen 33.12% of them finishing with a 3-1 score (405) and the remaining 21.01% have been closer with 3-2 scores (257).
