Japanese tennis player Naomi Osaka commented on reaching the semifinals of the tournament in Brisbane . “The coach said not to worry, although I was losing. I understood that she was playing cool, what else was there to do … I waited for my chance, and then I used it normally. I think that last season I would not have done it. But now I am confident and not afraid of anything. Before the US Open, I didn’t believe in myself, “Osaka quoted the press service of the Tour.
