All eyes turn to Adelaide as the ATP Tour prepares for the first Slam of the season, with players using the opening rounds to fine-tune their games under match pressure. The conditions are familiar, but early-season timing and sharpness can still decide tight contests. Day 1 offers a strong mix of established names and hungry challengers, setting the tone for what promises to be an intriguing week. As always, we break down the matches and give our predictions below.

ATP Adelaide Day 1 Predictions 
Daniel Altmaier vs Jaume Munar

Head-to-Head: Altmaier 2–2 Munar 

Altmaier is known for his physicality and willingness to grind, traits that can translate well even on hard courts when he’s timing the ball cleanly. Munar brings similar intensity but has historically been more comfortable on slower surfaces, where he has extra time to construct points. On quicker courts, Altmaier’s flatter hitting and ability to step inside the baseline could allow him to take control of key rallies. That slight advantage in court positioning may make the difference.
Prediction: Altmaier in 3 

Ugo Humbert vs Terence Atmane

Head-to-Head: first meeting 

Humbert’s left-handed serve and aggressive forehand are well suited to these quicker courts, and he generally starts seasons with confidence on hard courts. Atmane has plenty of upside but can be exposed when rallies speed up and pressure builds. Humbert’s ability to take the ball early and control the tempo should keep him a step ahead throughout.
Prediction: Humbert in 2 

Miomir Kecmanovic vs Valentin Vacherot

Head-to-Head: first meeting 

Kecmanovic’s strength lies in his consistency and ability to extend rallies without giving much away. Vacherot has been impressive since transitioning to the main Tour but faces a step up against a player who thrives on rhythm and patience. Over time, Kecmanovic’s depth and return game should apply constant pressure but Vacherot’s confidence should prove crucial. 
Prediction: Vacherot in 3 

Reilly Opelka vs Alexei Popyrin

Head-to-Head: Popyrin 1–0 Opelka

Opelka’s serve ensures he is never far from contention, particularly on hard courts, but rallies often swing on very fine margins. Popyrin has looked more well-rounded recently, moving well and backing himself in longer points. That added variety could help him navigate the big moments more effectively.
Prediction: Popyrin in 3 

Thanasi Kokkinakis vs Sebastian Korda

Head-to-Head: Korda 4–0 Kokkinakis

Kokkinakis will enjoy home support and has shown he can lift his level in Australia, especially when his serve is clicking. Korda, however, brings greater stability from the back of the court and is comfortable switching between defense and attack. In longer exchanges, his balance and shot tolerance may prove decisive.
Prediction: Korda in 3
