"I feel confident" - Kyrgios upbeat after another victory

Nick Kyrgios bested Adrian Mannarin oin a close match setting up a match against Rublev but he's feeling confident about his level.

Nick Kyrgios stayed hot in Miami with another straight-sets victory on Wednesday. His 7-6(3), 6-3 win did not come easy against the 'tricky' Mannarino. It was something that Kyrgios admitted after the match explaining:

"That first-serve percentage was key tonight. If I miss my first serve, he's going to be on the front foot from the early jump, and I couldn't afford to do that tonight against such a tricky opponent. The conditions tonight just did not help me at all," Kyrgios added. "I felt like I wasn't able to get him out of his comfort zone from the ground... I thought I returned extremely well."

His next opponent will be number 5 seed Andrey Rublev whom Kyrgios called an excellent player. Asked about the mathc he said he's confident:

"I grew up with him, I've seen him play. He's a hell of a player. Obviously we all know what he's capable of and I'm going into that match as a complete underdog. But I feel confident. If I'm serving well and playing well form the back I can beat anyone, and everyone knows that. I'm excited."
