Alexander Zverev has been showing great performances on his previous games matches, and I believed that this bet is advantageous. The analysis has been taking so relevant now, and he's worthy to win for this tournament because he had all the potential capabilities to create an overwhelming game play.
I am going with Medvedev today on hunch. This could be a bit biased because I didn't have a chance to see Zverev play in this tournament but Medvedev is a great player in fantastic form and I have a feeling he will get his first win against Zverev today. Their h2h is 4:0 in Zverev favor and it has start to correct a little bit since he is not that much better player. Hopefully today.
