Wimbledon has banned players from Russia and Belarus.
https://www.bbc.co.uk/sport/tennis/61161016Not sure I agree with this. Tennis (in most cases) is very different to, for example the Football World Cup or the Olympics. In the latter athletes compete under the banner of their country and formally represent their country, even in individual sports in the case of the Olympics. They are selected under the auspices of their country, wear kit of the country's team, receive medals in a ceremony with national anthem played and the flag of the country raised.
This is very different to Wimbledon where a competitor competes as themselves, in an individual sport - that they may be from a particular country seems irrelevant - they are not representing that country, they are representing themselves.
The Davis Cup is different, of course, but I'm not sure individual tennis players should be banned from competing in an individual tournament simply because they are Russian.
