John Isner says it's ridiculous Novak Djokovic isn't permitted to play US Open as of now.
The Russian is back on hard courts for the first time since spring.
"The ultimate goal that stays there for me is to absolutely come back to top 10," Grigor Dimitrov said.
Karolina Pliskova, John Isner, Barbora Krejcikova and Diego Schwartzman will sport new styles on court.
"I definitely feel like I'm playing [Top20] tennis. If not top 10, top 5 at the moment," says Nick Kyrgios.
"I think tennis have a good chance to be outside of politics because we have all the nations," Andrey Rublev said.
“Novak will do everything to be there, maybe he will get a special visa. But there are only two weeks," coach Goran Ivanisevic said of Novak Djokovic's US Open hopes.
