So I'm definitely looking forward to this 4th round. Djokovic/Medvedev. Nadal/Berdych. Berdych has looked really good. And though he has never had the success against Rafa that he's had against Fed, and Rafa has looked great, Berdych should feel fresh and could certainly push Rafa. Federer/Tsitsipas. Zverev/Raonic. Tiafoe/Dimitrov. Nishikori should do well against Carreno Busta. Who, is playing well and can challenge Nishikori. But Nishi is the better player. Cilic/Bautista Agut could actually be really good! And then I'm just glad to have Coric in the 4th round. Pouill or Popyrin doesn't really matter. He can probably beat or lose to both. So should be a good match. Probably not a bad match up in the bunch. I'm sure we'll see a drubbing somewhere. Either Medvedev won't be up to snuff against Djokovic or Tsitsipas won't be able to hand Fed. I could certainly be wrong and Nadal could drub Berdych as he has a number of times. Bautista Agut has only beaten Cilic once in 5 tries. But only one of the matches looks like it was all Cilic.
It's probably just that there are unknown factors in Medvedev and Tsitsipas against the top guys. And then Zverev can always implode, as can Coric. So a bunch of uncertainty for once. May all pan out like it normally does. Probably will. But should be entertaining along the way.
