Shelton easy?

The American escapes from the Mensik trap and launches into a tournament that is dear to him! Will he have his ups and downs again and come out in 3 or can he have a full match?

For a first confrontation between the two men, we lack a bit of information, but there is a key argument for me: the Argentinian is not going to much like taking concrete blocks in the face for 1h30. Even though his forehand is in place and the high bounce suits him, I think it's going to bore him after a while. He will lower his head to the ground with a nonchalant gait. This is also where he can be dangerous because the opponent lets his guard down, but Shelton has such energy that I don't believe in it for a cent.
