It really is a no brainer in terms of value. Even if she loses, no regrets about the choice.
The Russian is an old school player and to be honest, it's a surprise that she is still here. But then, Rybakina is on day to day basis and even in the doubles she looked like shit, Aza is a has been, Sabalenka lacked testosterone in the match, Tomljanovic is just an average player and McHale is Challenger material.
On the other side, Zidansek, won against Badosa, but then this bitch was so bad in important moments - you don't need a wild guess to judge where I did put my money last round. Cirstea is a proper all round player, Siniakova is an incredible defensive player, Brengele is just an average girl and Andreescu is simply not fit.
All in all, Pavlyuchenkova will try to aggress Zidansek as this is her gameplay but the Slovenian showed extreme resistance at the baseline and I don't think that she will be outplayed. Both players are in prime form and I think Zidansek is less error-prone that the opponent. I frankly think that this is a 50/50 affair, as such, the right choice is to take the underdog. Let' see.
