Roddick on Rublev: "I don't find it funny".

Beaten by Alexander Zverev on Monday, Andrey Rublev will now face a Carlos Alcaraz who is sick and tired of his opening loss to Casper Ruud, in a bid to preserve his chances of qualification.

Scheduled for no earlier than 2pm, the match promises to be a hard-fought affair that could well test the Russian's fragile nerves.

Much loved on the circuit, but also infamous for his sometimes violent outbursts of temper, Rublev has a hard time controlling his emotions on the tennis court.

Asked about the world number 8's behavior, which sometimes goes as far as self-mutilation, Andy Roddick recently expressed his concern: "I watch his outbursts of anger and I don't find it funny.

I really like Andrey Rublev. Everybody in the locker room likes Andrey Rublev a lot, and he's one of the most popular players on the circuit.

It's not like we're picking on Rublev, it comes from a real concern. And if you hit yourself, would you get a warning?

If you break your racket on the court, you get a warning, but I feel that breaking your racket on the court is a lesser evil compared to self-mutilation on the court."
