Alexander Zverev defeated Borna Coric 6-4 6-4 to reach the Miami Open semifinals for the first time in his career. The German player thinks he is getting closer to his best level after a relatively poor start to the season: 'I don’t think I’m far away at all. The beginning of the seasons are very tough for me because I’m someone who does a lot of physical work in the off season and I have to get used to my new body', the world No. 5 said. 'I put on about 4kg - I’m heavier than I was, stronger than I was and it influences your tennis. It just takes time.'
Analyzing his most recent win, Zverev added: 'You have to win every single point against him yourself. That's what I did tonight, and I'm very happy with it.'
He finally previewed the semifinals against Pablo Carreno Busta: 'Very difficult match', he admitted. 'I think he's playing very well right now. He played well in Indian Wells, playing well here. It doesn't get any easier. But it's a Masters . We know that it's not going to get easier, and I'm looking forward to it.'
