Zverev on Sinner: 'Different level' challenge

After dropping just one set in his Miami Open run so far, Zverev knows he faces a significant challenge against world number two Sinner. 'In all matches I try to use this tool, but against Jannik it will be more difficult than against others,' Zverev said, highlighting Sinner's highest average ball speed on the ATP circuit.

The German has lost six straight meetings to Sinner and only won four of their 11 ATP Tour matchups, though he did secure a five-set victory in New York last September. 'We've had very good matches in recent years, very close matches in the past few months. It's true that he has won them all, so I hope that this time there will be a different outcome,' Zverev added.
