A much needed win for Thiem over an in-form opponent. This is his first top 20 win this season. Hopefully he's out of his slump now.
All of his three other wins over Zverev came on clay so it's good for Thiem to prove that he can get the win over Zverev on hard court as well.
Is Alex playing Dubai?
No. He plays Marseille next week and Acapulco the week after that.
Interestingly enough, Thiem, Zverev, and Karlovic are the only players in the top 20 playing every week this month.
