Zverev A. vs Medvedev D. prediction

ATP - SINGLES: St. Petersburg (Russia), hard (indoor) - 1/8 final Atp second round of St. Petersburg, the German Alexander Zverev and Russian Daniil Medvedev face. Party at my very attractive option, both are young promises and no doubt go far, first is the German, who is doing a good year, although in recent months that low intensity and lost a little pace wearing on the hard achievement to win 16 games and lost 14, irregular numbers and is the last tournament has not gone well, fell in the first round in Toronto, also lost in the first round in Cincinnati and finally in the US Open failed to pass the second round where he was eliminated before Evans. Russian Medvedev is a player that adapts to all surfaces, this year has a balance 35 wins and 16 losses, on tracks hard has won 19 games and lost only 6 times on the clay won 10 and fell 7 opportunities and finally on the grass victory secured 6 and lost in 3 opportunities, the truth is having a very good year, and the numbers speak tennis. Well both come here differently, Zverev won first encounter a Khachanov who played him against the head, I think if he had not unfocused could do something more, a player when he was in trouble I manage to try to trace the game with winners and I think that he played a lot against and Alexander was a gift because it was not going so well the first set, as I said the second set after breaking the Russian Khachanov practically throw the match. Medvedev comes here, having won 3 games, only the first one dropped a set before Vatutin, then won the next 2 2-0. The key to this meeting more than Medvedev is local will be the rally, Alexander is a player who as I said before, seems to have lost some pace and consistency in his punches, very different game from Russian, a player accustomed to the rallies, handles very good passing and runs the entire track, as to remove both have similar styles, the difference is in how they play in the rest, and Zverev lately is depending more service than their rest, Medvedev is a player who relies play in the rest but has a good ally that is the serve and I think against a player like German comes in handy. First time you face, I think the fee in my opinion is very high, but not the reason why rose more as it was between 2.50 and 2.62 and now went to more than 3, well I still like to always try players like these and more just knowing that his rival is returning to meet his good tennis beginning of the year, let's go with the +3.5 handicap for not risking too much, just paid very well.
