De Minaur is showing good form in practice and is ready to compete for the win. Medvedev's opponent is unsure in his game, which is evident from his recent performances. De Minaur has quick feet and a strong serve, which could pose a problem for Medvedev with his inconsistent play. In this situation, De Minaur is more likely to come out on top.
In the game between Medvedev and Demon, an exciting competition is expected. Both tennis players are showing high-quality game, and considering Medvedev's instability without his first serve, the match could be unpredictable. It is likely that both players will showcase their best sides, leading to a higher number of games. Therefore, my prediction is total over 23 games.
I predict that Daniil Medvedev will defeat Alex de Minaur. The Australian is under excessive pressure, showing his best tennis in losing matches. Unlike Americans, who falter in key moments. Medvedev is more experienced and doesn't succumb to the same pressure, giving him the advantage throughout the match.
