Karen Khachanov is not doing great this year. It was a two setter win for Medvedev against Rublev, I was expecting that Rublev will give Medvedev a hard time but it was sort of an easy win.
So semi finals: Medvedev vs Gerasimov, Coric vs Sousa
Coric again made a comeback victory against Ruud, while Sousa defeated the former champion Kukushkin.
Medvedev is on a roll right now, I think he still has the momentum from last month's US Open and it seems playing high and intelligent tennis. With that said, I wouldn't be surprised if he goes to win this year's St. Petersburg.
Medvedev vs Couric in the finals will be good.
Yes he is a roll right now and if he wins this tournament he will be one step closer to catching Federer for that number 3 ranking. Its looking like he will catch Federer at this stage as Federer might not play in as many tournaments now and get himself for next year which I'm thinking could be Federer's final year. If Medvedev does finish in the top 3 it would be a huge achievement for a young player to do so in a year which has been dominated by Nadal, Djokovic and Federer.
