Kei Nishikori vs Flavio Cobolli

Kei Nishikori would likely be the favorite in this matchup, thanks to his experience, consistency, and high-level performances in the past. Nishikori's ability to return well and stay patient in rallies would be a big advantage against Cobolli, who is still developing his game.

Flavio Cobolli, while a promising young player, would likely struggle to handle Nishikori's consistency and depth from the baseline. Cobolli might be able to test Nishikori at times, especially if he can impose his own pace, but Nishikori's experience and movement would likely prevail.
