Ajla Tomljanovic reversed her recent fortunes against Simona Waltert, winning 6-3, 6-4 in the Miami Open Round of 128 on Tuesday. The Australian dominated on serve, winning 77% of first serve points compared to Waltert’s 56%, to avenge a lopsided 6-4, 6-0 defeat just six weeks earlier in Singapore.
The match turned on Tomljanovic’s ability to neutralize Waltert’s serve. Despite entering with superior ace averages (3.4 per match to Tomljanovic’s 2.5), the Swiss player managed just one ace while Tomljanovic fired three. More critically, Tomljanovic won 77 total points to Waltert’s 64, controlling rallies with the authority that has historically made her dangerous on hard courts—where she owns a career win over Aryna Sabalenka at this very tournament.
Waltert struggled to replicate the dominance she’d shown in their Singapore encounter, winning just 57% of second serve points despite committing zero double faults. Tomljanovic’s cleaner service performance (71% first serves in) and superior first-serve effectiveness sealed both sets without facing a single break point.
Key Takeaways
- Tomljanovic’s first serve was the difference-maker: her 77% win rate on first serve points dwarfed Waltert’s 56%, building a foundation that neutralized the Swiss player’s typically aggressive return game.
- The Australian landed 71% of first serves, eight percentage points higher than Waltert’s 63%, ensuring she rarely faced vulnerable second-serve situations where Waltert actually held a slight edge (57% to 47%).
- Despite Waltert’s flawless service motion (zero double faults), she managed just one ace—well below her recent average of 3.4 per match on hard courts—suggesting Tomljanovic positioned herself aggressively to neutralize free points.
- Neither player faced a break point in the entire match, underscoring how Tomljanovic’s superior first-serve effectiveness (77% vs 56%) proved decisive in a contest where service holds determined the outcome.
Player Analysis
Ajla Tomljanovic
The Australian’s serving clinic represented a tactical masterclass against an opponent who had dismantled her just six weeks earlier. By landing 71% of first serves and winning more than three-quarters of those points, Tomljanovic denied Waltert the baseline opportunities that fueled her 6-0 second-set rout in Singapore. Her three aces arrived at crucial moments, and crucially, she limited double faults to just two—a significant improvement over her recent average of 6.1 per match on hard courts.
What made this performance particularly impressive was Tomljanovic’s ability to protect her second serve despite winning just 47% of those points. She simply didn’t allow Waltert enough looks at it, a strategic adjustment that suggested careful match preparation. With 108 career hard-court wins and a history of producing upsets at Miami (including that 2019 victory over Sabalenka), she looked every bit the experienced campaigner.
Simona Waltert
The Swiss player couldn’t recapture the magic from Singapore, where she’d bageled Tomljanovic in the second set. Her normally reliable serve—averaging 3.4 aces per match recently—produced just one ace here, and more damagingly, she won only 56% of first-serve points. That’s a catastrophic drop-off for a player whose game relies on holding serve comfortably and applying pressure through aggressive returns.
Waltert did manage to avoid double faults entirely and actually won more second-serve points (57%) than her opponent, but those positives couldn’t overcome the fundamental deficit on first serves. Making her Miami debut without prior tournament experience at this Masters-level event, she appeared tentative at key moments, never earning a single break-point opportunity despite Tomljanovic’s modest 47% second-serve win rate.
