This looks up to be a very interesting match. We can’t pass anything on Cibulkova’s game after her win against Wozniacki because Caroline played like she had no motivation. And Kasatkina easily defeated Laura Siegemund. But I wouldn’t risk backing Kasatkina, even if she’s able to offer a battle. Cibulkova’s solid play shouldn’t confuse Kasatkina. Dominica feels uncomfy against the younger players, so she can become nervous.
And there is one more thing: the coach who trained Cibulkova since her childhood and moved her into the top rankings is now training Daria Kasatkina. So he knows Cibulkova from head to toe. And this is not so easy to see your previous ally now working with your rival. So Cibulkova will feel psychologically vulnerable. And Kasatkina has nothing to lose now, that’s why the match should be slashing. I expect total match games over 21.5 here.
