In the Medvedev - Sinner match, I predict the total over. Both players are in good form, so a lot of games are expected. Daniil can push the favorite to a tough match and make it interesting. It will be difficult for Sinner to outplay the Russian player, so Medvedev can hold on and make the match tense. I assume that at least one set will end with a score of 7:6 due to Medvedev's serving errors.
