Title holder in trouble?

Jakub Mensik won, but took a while to get into the match because of a lack of rhythm due to the little virus he picked up at IW... Opportunity for Tiafoe?

Not easy. Maybe it was that first round that was dangerous for him, and now he’s back in the right groove. Because during sets 2 and 3, it was much better against Walton. Because if he plays well, I can already hear Marcos saying, "Careful, big server and a guy who knows how to attack, bad match-up for Tiafoe!". It’s true that the American makes his living off his aggression on second-serve returns, his changes of direction during rallies, taking the ball early... But when he’s facing an excellent server, there’s very little room for him given his overall returning quality. Whereas a lot more of his own service points will be fiercely contested. We saw that against Zverev 10 days ago. And if Mensik is in form, same story for me. Only, there are the doubts we all know...
