Based on the information provided, a prediction can be made for the match between Zverev and Medvedev. Although Zverev does not have a good record against opponents this year, he did start the tournament with a win over Musetti. It is important to note that Musetti is not a strong player on hard courts, but the victory helped Zverev regain confidence. In his recent matches against Dimitrov and Nishioka, Zverev showed good play and had several aces against each opponent. It is also worth mentioning that his serve return has become a strong point, which is crucial on hard courts. Meanwhile, Medvedev recently lost to Mannarino, which could indicate that he is not in the best form. As a result, taking into account all these factors, I lean towards the assumption that Zverev has a better chance of winning this match against Medvedev.
