The 2026 tennis season is set to commence on January 2, with the United Cup taking center stage in Perth, Australia. The first day of competition will feature matchups between teams from Spain, Argentina, Greece, and Japan, showcasing notable players like Jaume Munar and Stefanos Tsitsipas.
In the first clash of the day, Spanish player Jaume Munar will face off against Argentina’s Sebastian Baez. This will mark the third meeting between the two, with both players having won one match each in their previous encounters. Munar’s victory in the 2021 Buenos Aires qualifying came via retirement from Baez, while the Argentinian claimed a straight-sets win during the 2024 Golden Swing in Santiago.
Looking at Munar’s performance in 2025, he enjoyed a solid year, climbing to the No. 33 spot in global rankings, positioning him favorably ahead of the Australian Open. He ended his previous season contributing to Spain in the Davis Cup Finals, where despite a 1-2 record, he displayed commendable form in all three matches he contested. In contrast, Baez struggled, finishing with a disappointing 17-24 record, and has often found it challenging to assert his game outside clay courts.
Prediction: Munar in straight sets.
Stefanos Tsitsipas, the Greek tennis star, will also be in action as he prepares to match up against Shintaro Mochizuki from Japan. Tsitsipas, currently ranked 36th in the world, is coming off a turbulent 2025 season, ending in September, which has left him unseeded entering Melbourne. However, a break from competition could provide him with the much-needed rest and recovery ahead of this new season. Tsitsipas has a rich experience representing Greece in the United Cup, boasting a 6-2 singles record.
Mochizuki, a rising talent from Japan and formerly an exceptional junior player, is stepping onto the main tour with a professional ranking of No. 99. Despite his promising junior background, he has only secured seven wins on the main tour thus far and will face the added pressure of his first United Cup experience. Although Tsitsipas has not been in top form, he is expected to have the advantage over Mochizuki.
Prediction: Tsitsipas in straight sets.
The day promises thrilling encounters as these athletes aim to set the tone for their respective nations in the United Cup, looking to build momentum heading into the Australian Open.
