Nikoloz Basilashvili (+1.5 sets) to beat Alexander Zverev at 3.38 with Pinnacle
This will be the first challenge for Zverev, hard to gauge where he's at based on his matches against Lu and Galan, who are poor by ATP standards. Basilashvili did well against Sonego and he has that upset potential in him. I wouldn't play this at 2.50, but I'm more than happy to back the upset at 3.38. It's just a set, after all.

Stefano Travaglia to beat Holger Rune at 1.93 with Pinnacle
Rune seems ripe for a letdown somewhere and his performance against Martin wasn't too convincing. Travaglia has a poor form this year, but, to be fair, he was playing main events instead of Challengers like Rune. This looks like a good opportunity to get somewhere and I think he's still the better player of the two all things considered.

Steve Johnson (+1.5 sets) to beat Taylor Fritz at 1.76 with Pinnacle
I backed Johnson against Fritz back in Wimbledon and I'm willing to do the same here. Fritz played an epic against Marchenko that also finished late in the night. He looked tired, ready to go to the deciding tie-break, but Marchenko spared him that and produced two double faults in a row to get himself broken. Johnson has a decent record against guys with big serve and should be fresh here. Also wanting to get some revenge for Wimbledon for sure. Fritz is the favorite no doubt, but the odds for Johnson not to lose 0-2 look juicy to me.

Danilovic has improved, but perhaps not as much to warrant those odds. Haven't seen either lately though.

Marc Polmans (+5.5) to beat Christian Garin at 1.73 with Pinnacle
Garin has been off the boil a bit lately and he's got some history with Polmans as well. Two tight Grand Slam matches, with one coming in this past Wimbledon. Polmans was trying to make a big comeback there and wasn't too far, I bet he will be pumped up for this. If Garin starts slow or isn't on the top of his game, that could very well spell trouble. It's not often that we get 5.5 or 6.5 lines in men's tennis, but I'm happy to take them if the circumstances look right. Riedi delivered, let's hope Polmans can do as well.

Dominic Stephan Stricker to beat Arthur Rinderknech at 2.20 with Unibet
I'll also go for the other big Swiss prospect. We all know what he's capable of in Switzerland, so I wouldn't read into his average form that much. That's how youngsters tend to play, do well when faced with a challenge and then lose to someone worse in a Challenger. 

Leandro Riedi (+6.5) to beat Federico Delbonis at 1.91 with Unibet
Swiss tennis will have to start working without Federer and Wawrinka soon, with Stricker and Riedi being the most promising talents at the moment. Stricker has already made a name for himself, while Riedi needs to step out of the juniors and do some damage. He's just 18, but I've seen him twice this year and he's a good prospect. In front of his home crowd, I think the handicap can be taken care of.
