Based on the recent results, Alex De Minaur and Alexander Zverev, it can be assumed that De Minaur is in good form and showing consistent performances. His easy victory over Medvedev indicates high confidence in his game. Meanwhile, Zverev, despite the win, faced difficulties against a weaker opponent. This may suggest potential issues in his game. Therefore, it is likely that De Minaur is currently in better form and will be more successful in the next stage of the tournament.
