Frustrated with himself and others, lacking arguments to find his tennis and tired of a dangerous drift. This is how Stefanos Tsitsipas has looked for some time, but what he showed at the US Open 2025 was a step further. He succumbed to Daniel Altmaier and reproached him with a childish attitude for serving underhand at times during the match.
A shadow of his former self. Stefanos Tsitsipas has been losing matches, level of play, ranking, but above all, his identity as a tennis player for months. This is the most dangerous aspect, placing the Greek in a truly tricky present and future situation. His tennis is unrecognizable, lacking ideas to return to being the player firmly positioned among the best and an aspirant to everything, and his attitude towards himself and opponents is increasingly incomprehensible. In a memorable five-set battle against Daniel Altmaier, he was eliminated from the US Open 2025 and displayed his worst version in terms of fair play.
- The final result was 7-6 (5) 1-6 4-6 6-3 7-5 in favor of Altmaier over Tsitsipas
The experienced German player knew how to maximize his strengths at all times. Aware of his opponent's emotional instability, he sought constant rhythm changes using his natural talent and skilled hand. Among these technical resources, in the fourth set, he included several underarm serves, well-established lately on the circuit and accepted by all as part of the game.

There is nothing offensive in executing a stroke that requires exquisite skill and poses a huge risk for the one who does it. However, the Greek tennis player took it as an offense. Most surprisingly, at the moment, he did not show his anger, beyond hitting a ball towards the opponent's body during the match for which he apologized, as usual. It was only at the end of the match when he decided to reproach the German with strong words for his attitude.
- Tsitsipas displayed poor sportsmanship by reproaching Altmaier for serving underhand
"Next time, don’t wonder why I hit you in the body, okay? No, I'm just saying that if you serve underhand...". At that moment, one can see an enraged child looking for trouble when it's uncalled for, Stefanos Tsitsipas, and a triumphant adult avoiding any confrontation by walking away without wanting to hear anything, leaving the Greek in a compromised position. A tough blow for a man who has 20 wins and 17 losses this year and has not won two consecutive matches since the Conde de Godó, with his title in Dubai being the main support for his position in the top-30, an status still threatened in this US Open 2025. Kudos to Daniel Altmaier for his handling of the situation.
