Bencic new ranking after beating petra dubai duty

I think there may be a few assumptions in your question that don't quite add up.

Firstly, Belinda Bencic is a professional tennis player, but I'm not aware of her ever playing a match against Petra Dubaj (I assume you meant Petra Kvitová, a Czech professional tennis player).

Secondly, Dubai Duty Free Tennis Championships is a real tennis tournament, but I'm not aware of Belinda Bencic ever playing a match against Petra Kvitová in that tournament.

Lastly, even if Belinda Bencic did play a match against Petra Kvitová in Dubai, it's unlikely that her ranking would be directly affected by the outcome of that match, as the WTA rankings are calculated based on a player's performance over a longer period of time.

If you could provide more context or clarify which match or tournament you're referring to, I'd be happy to try and help you with your question!
