The same could be said of Ilya Ivashka, who is the lone Belarusian left in singles following Aryna Sabalenka's surprise second-round defeat.Ivashka has played some of the best tennis of his career in recent months. He blasted his way into the fourth round of Wimbledon before losing to the in-form Italian Matteo Berrettini.Ilya IvashkaHe has carried that momentum into Tokyo, where he has registered two impressive victories. But If the Belarusian intends to extend his stay in the Japanese city, he will need to hit his spots consistently with his monstrous first serve against Nishikori. Nishikori is a versatile baseliner with a reliable double-hander that cannot be easily punctured. He also has an extra incentive to perform, considering he is playing on home soil. While he looked far from his vintage best against Giron, he is undoubtedly the superior player when compared to Ivashka and should hold an edge over the dangerous Belarusian.Prediction: Kei Nishikori to win in three sets.
