Krajicek looks tempting at these odds. He played some decent tennis on this level, since the start of the season, despite being more or less challenger level player before. I like him here, mostly because Istomin is garbage lately. He was unreliable and inconsistant before, but lately it got eeven worst and he is simply bad. I don't really know what's his deal. He seems to have all the tools to be much more succsesful then he is, but never really got over the hump. Going from talented player to a good one. I think his problem might be coach. He is coached by his mom since the start of his career and I believe that change would be great for him, but he doesn't share that thought obviously.
Schwartzman also looks decent here. He is probably such a big dog, because he is considered as clay court specialist, which isn't fully true imho. He can give a good effort on hard as well, espcially on such slower bouncy ones, like in IW. With Jerzy, you never really know what you are getting and he never really thrived on outdoor hard.
