Bernard Tomic slams Australian Open balls, takes dig at Nick Kyrgios

is never banal when he gives interviews. And his chat to the reporters after his three-set win over Jack Sock at the Kooyong Classic on Tuesday was another proof. Tomic was highly disappointed with the Australian Open balls that are used in Kooyong and in most of the warm-up Melbourne events.

I dont know what the Australian Open has done, but it is terrible, Tomic said. I dont know too much [about the balls], but I dont feel like it is that good of a ball. I think theyre pretty cheap from what Ive heard.

Tomic, who won mixed doubles match against his sister Sara, also said he feels confident for the short term future: For practice its unbelievable and Ive got some stuff Ive got to work on and tomorrows my last chance I can do that.

Am I doing that against Nick, who only just serves, its tough to do, so hopefully he takes it seriously. On his performance with Sara, Bernard concluded: I think we played pretty well today, we didnt play that aggressive but I was pretty happy.

I dont run a lot anyway but the last thing you want is to run for a ball and then you cant do anything five or six days later. Tomic looks forward to facing Nick Kyrgios at the Kooyong Classic on Wednesday.

Were good friends and its good for us to play hes needing it more than anything because hes a little bit mentally struggling right now. On his expectations for the Australian Open, Tomic added: Probably another third or fourth round like Ive done a hundred times.

Sometimes its good to not be seeded and sometimes its bad so well see in two days. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
