Opelka R vs Young D prediction

ATP - SINGLES: Atlanta (USA), hard - Quarterfinals. 2 compatriots face, on the one hand the 18-year Opekla Reilly and another young Donald. Sure many will be set in the ranking of the players when making a bet and it is clear because it is logical, but there are occasions where there are surprises and more in tennis is so unpredictable. For this meeting the young Reilly occupying the rank 837 and at 18 I noticed you have a pretty good game and its great height is more than clear that it is a punch. I had the opportunity to see him play against Anderson and this meeting had also discussed and finally decided to give the young man who gave me the green. The fact is that Opelka despite his good serve, the rest does not hurt, it's like a mixture of Querrey and Isner, I've noticed a lot like the game both serve as rest and even physically resembles Isner haha. I think his young age I have no doubt that the United States will have another player good serve. Anderson and Young have like, I mean mentally when something goes well much lower performance and often will take its toll on the party that leads to defeat. Perhaps Young has a better rest than Anderson, but it is also a player who makes a lot of unforced errors, Opelka is clear that your weapon will serve and will try to take advantage of the break situations that may arise. Young has a decent kick so there will be many games rally so I hope you will seize these occasions Reilly. Another thing I noticed in the young American is that despite his age not give up until the last point is played, I say it because Anderson was losing 5-4 in the final set and the South African he pulled to win, except 2 match point and then have 2 break opportunities but taking the latter to then win the game, return to break and serve for the match, having much head leaving blank the South African in the latter game. So this time I will go with the young, I'm not going to because I beat Anderson or seek the surprise, I think in these games if there is some chance that you can win, because no faces Nole and Federer, that if it would be a surprise, I have confidence, I hope to make a good game and give us the green.
