Andrey Rublev endured a really brutal match against Daniil Medvedev at the 2023 US Open, but he wasn't thinking about the conditions that much during the match.
Rublev is a very passionate player who wears his emotions pretty openly. You'll never be unsure what Rublev feels when watching a match of his because he's very expressive and vocal, among other things.
Medvedev is a similar player, and we've seen both of them show plenty of emotions during their brutal US Open quarterfinal. Besides neither playing their best tennis, both players struggled with the conditions, though Medvedev was far more vocal about it.
He even told the camera that a player would 'die' if the sport kept pushing players to play in such conditions. Rublev was asked about it and confirmed that he didn't even think about that.
No, I'm not even thinking about my health. I don't know. At this moment, these moments I'm thinking that, I don't know, I need to fight. Doesn't matter how is tough. I mean, the sport is not easy. And you need to be ready for everything that can happen. In the end, I don't know. In the end, the best players, they prove that they are ready, and that's why they are the best.
So I don't know. Yesterday Novak was playing in the same conditions, and nothing happened and he was able to win still the match against really a good player, against Taylor. But I feel it is really tough to beat him with his serve, and he was able to manage it really well. So there is something about the best players, they do better or they ready better
The conversation Medvedev opened up is a valid one and even Djokovic talked about the conditions but Rublev is right that the best tend to adapt and keep pushing. Whether that's healthy or not is a different but valid question.
