This enabled Sinner to break a Roger Federer record after winning his third consecutive hard court major.

While Sinner was celebrating his Australian Open title defence, Zverev looked very dejected after losing his third major final in a row.

After a fortnight of thrilling action in Melbourne, The Tennis Gazette has picked out five of the biggest winners and losers from the Australian Open.

Madison Keys – Winner

There could only be one first choice of winner at the Australian Open this year, with Madison Keys winning her maiden Grand Slam title after beating world number one Aryna Sabalenka in the final.

Sabalenka was not the only obstacle that Keys had to overcome, having also beaten Elena Rybakina, Elina Svitolina, Danielle Collins and saved a match point against Iga Swiatek in the semi-finals.

Keys’ victory has elicited a strong response, with the American receiving messages of congratulations from around the globe.

As a result of her first major win, Keys has returned to the top 10 and matched her career-high ranking of world number seven.

Stefanos Tsitsipas – Loser

Early Grand Slam losses have started to become a bit of a trend for Stefanos Tsitsipas, who was beaten in the first round by Alex Michelsen.

Michelsen had beaten Tsitsipas in their only meeting prior to this match, and continued his 100% recorrd against the Greek at the Australian Open.

This is the second consecutive Grand Slam tournament that Tsitsipas has lost in the first round, with his last Grand Slam match win coming in the first round of Wimbledon against Taro Daniel.

It is quite the fall from grace for the two-time Grand Slam finalist and former world number three.

Paula Badosa – Winner

Thankfully for Tsitsipas there was something to celebrate, as his girlfriend Paula Badosa reached the Australian Open semi-finals for the first time.

This included a big upset win over one of the title favourites in Coco Gauff, with Badosa beating the world number three in straight sets.

Badosa nearly quit tennis last year due to a back injury, but has since been able to climb from world number 140 to a top 10 return in just nine months.

The Spaniard could not make it to the final after being beaten by her good friend Sabalenka, but it was still a positive tournament nonetheless for Badosa.

Daniil Medvedev – Loser

Daniil Medvedev has been a set away from winning the Australian Open title in two separate finals in recent years, but was unable to get anywhere near in 2025.

Medvedev broke the net camera in his first round match, where he survived against world number 418 Kasidit Samrej in five sets.

The former world number one then found himself embroiled in another battle with promising young American Learner Tien.

Medvedev took the match to a fifth and deciding set after trailing Tien, but was unable to make his hard work count after losing in a tie-break.

To make matters worse for Medvedev, the match finished at 2:55am and he was subsequently fined $72,000 for his on-court behaviour.

Learner Tien – Winner

Not only did Tien get his first top 10 win over Medvedev, the teenager also managed to overcome the late finish and win his next match against Corentin Moutet.

Tien’s run came to an end against Lorenzo Sonego, but the American certainly made a strong impression in his first appearance at the Australian Open.

As a reward for his run in Melbourne, Tien is now at a career-high ranking and inside the top 100.

Qinwen Zheng – Loser

Qinwen Zheng reached her first Grand Slam final at the Australian Open last year, and came into this year’s event as the fifth seed.

Some were even picking Zheng to win the Australian Open, but she found herself being knocked out in just the second round.

After losing in straight sets to 36-year-old Laura Siegemund, Zheng crashed out of the tournament and has subsequently dropped 1,230 ranking points.

Joao Fonseca – Winner

In the first week of the Australian Open, Joao Fonseca was the talk of the town after making his senior Grand Slam debut.

The Brazilian was on a 13-match winning streak coming into the tournament, where he would play top 10 player Andrey Rublev in the first round.

Fonseca lived up to his hype and beat Rublev in straight sets with a hugely impressive performance that appeared to stop people in their tracks.

Some people were even predicting Fonseca to qualify for the ATP Finals this year, but the 18-year-old was beaten by the aforementioned Sonego in his following match.

This recent run of form has certainly played dividend, as Fonseca is now a top 100 player for the first time.

Casper Ruud – Loser

Casper Ruud is a three-time Grand Slam finalist, but was one of the top seeded players to suffer an early defeat at this year’s Australian Open.

This was not a complete shock to some, who had suggested Ruud could lose early at the Melbourne major.

Ruud’s exit was sealed at the hands of a second round defeat to 19-year-old Jakub Mensik.

Despite this disappointment, Ruud has somehow risen in the rankings after the Australian Open to world number five.

Eva Lys – Winner

Lucky loser is the perfect way to describe Eva Lys’ surprising run to the fourth round of the Australian Open.

Lys had lost in the last round of qualifying to Destanee Aiava, but found herself as a last-minute main draw replacement after Anna Kalinskaya withdrew due to injury.

The German really took advantage of this, winning three consecutive matches at a Grand Slam for the first time.

Lys’ run came to an end at the hands of a dominant Swiatek performance, but the 23-year-old has lots to be positive about after breaking into the top 100.

Victoria Azarenka – Loser

Victoria Azarenka has enjoyed plenty of happy memories at Melbourne Park before as a two-time champion, but the former number one looked far away from that player in her 2025 match.

In her 17th appearance at the Australian Open, Azarenka lost to Italian Lucia Bronzetti in the first round.

Despite no longer being in the tournament, it appeared that the Belarusian was still keeping a close eye on the Australian Open with Azarenka commenting on Novak Djokovic’s controversy after he refused an on-court interview with Jim Courier.
