Vit Kopriva reached his first ATP semifinal of 2026 with a commanding 6-4, 6-4 victory over Juan Manuel Cerundolo in the ATP Rio de Janeiro quarterfinals on Friday. The Czech’s dominant first serve proved decisive on the Brazilian clay, winning 86% of those points while converting two crucial break points to seal the straight-sets win in just over 90 minutes.
Kopriva established control early, breaking Cerundolo’s serve once in each set while never facing a break point himself. The 28-year-old struck six aces to his opponent’s three and unleashed 21 winners, more than doubling Cerundolo’s output of 10. Despite committing 32 unforced errors to Cerundolo’s 30, Kopriva’s aggressive approach paid dividends when it mattered most, particularly when his first serve found the box.
The Argentine struggled to generate any return pressure, failing to create a single break point opportunity across the entire match. Cerundolo’s 65% success rate on first-serve points wasn’t enough to stay competitive, and his inability to make inroads on return left him chasing the match from start to finish. Kopriva closed out the victory with authority, sealing the second set 6-4 to book his spot in the final four.
Key Takeaways
- Kopriva’s first serve was the difference-maker, winning 86% of first-serve points compared to Cerundolo’s 65% — a 21-percentage-point gap that proved insurmountable on clay.
- The Czech’s ability to protect serve was absolute: he didn’t face a single break point in the entire match, converting 2 of his 8 opportunities to claim both sets.
- Kopriva doubled Cerundolo’s winner count (21 to 10), demonstrating superior shot-making despite committing slightly more unforced errors (32 to 30).
- The 11-point margin in total points won (69-58) reflected Kopriva’s control throughout, never allowing the Argentine a foothold in either set.
Player Analysis
Vit Kopriva
The Czech played percentage tennis at its finest, building his victory on the foundation of an elite first-serve performance. His 86% win rate when landing the first ball in play gave Cerundolo virtually no opportunities to attack, and Kopriva capitalized by taking the initiative with 21 winners. The six aces helped him navigate service games without stress, and his disciplined return game — converting two of eight break chances — was enough to seize control of both sets. While 32 unforced errors suggest some looseness, Kopriva’s willingness to play aggressively from the baseline kept Cerundolo pinned behind the baseline.
Juan Manuel Cerundolo
The Argentine simply couldn’t find a way to pressure Kopriva’s serve, failing to create even a single break point across 12 service games. His 65% first-serve points won was respectable in isolation, but not nearly enough against an opponent firing on all cylinders. Cerundolo’s 10 winners told the story of a player unable to dictate rallies, and his 52% success rate on second-serve points — typically a strength for clay specialists — couldn’t compensate for his passive return performance. With no break point opportunities manufactured, Cerundolo was left to rue missed chances that never materialized.
