Wang Q. - Yastremska D.

Even though Kostiuk has already gone quite far and has the ability to beat players with a high ranking, her skills tend to decline in the first three stages, as she then becomes tired due to her aggressive attacking style in tennis. In the first set of the game against Kessler, there were a lot of unforced errors. On the other hand, Ukraine has already played three consecutive matches in Montreal under the sun, and Ghana has been a burden. Rybakina, no matter what, only because of her powerful serves and her ability to win points with her strength, already has a big advantage. Even in the game against Yastremska of Ukraine, it seemed more solid than Kostiuk and Kessler. The only place where I see a disadvantage here is that the last two H2H matches went in Rybakina's favor, but I believe that Kostiuk will have exhausted most of her energy in attack.

Although Kostiuk has already gone quite far and has the ability to defeat players with high rankings, her abilities are typically more prominent in the first three stages, as later on it seems she struggles, as she plays a very aggressive attacking style of tennis. In the first set of the game with Kessler, there were numerous unforced errors. On the other hand, Ukraine has already played three consecutive matches under the hot Montreal sun, causing fatigue. Rybakina, regardless of her powerful serves and forceful shots, has a significant advantage. Even in her game with Yastremska, Rybakina seemed more solid than Kostiuk with Kessler. The only downfall I can find is that the last two H2H sets were in Rybakina's favor, but I believe Kostiuk has already used up most of her energy in offense.
