Zverev’s got a solid chance to take this 2-0 against Humbert. His serve is a real weapon, and if he’s on his game, Humbert’s going to have a hard time breaking him or even keeping up in rallies. Plus, Zverev’s been in way more high-pressure matches, so he’s got the experience to stay calm and close it out. Unless Humbert pulls something surprising, Zverev’s consistency and power should be enough to get it done in straight sets.
