I don't think he's beating Zverev, he's playing well and been having relatively easy matches compared to Nick..
Much needed week, still don't think it means a whole lot, i think it's been the right set of circumstances that have helped his week with the crowd and matchups, he usually matches up well with Nadal and Wawrinka. Not usually so much with Isner so makes that impressive
How is Zverev considered the next best thing? Haven’t seen much from him to impress. He’s tall, not as mobile and has limited tools to his game. He’s strong and has power yes, but that’s it. That’s my opinion anyway
