A spot in the next round is at stake on Friday, when Alexander Zverev goes up against Arthur Fery in the Vienna quarterfinal. Alexander Zverev is 8-2 across recent matches. Arthur Fery comes in at 5 wins from the last ten.

There is no history here: this is their first tour-level meeting.

Hold strength tells the story — 73.7% versus 68.8% on first-serve points in Zverev's favor. Anything other than a Zverev win would rank among the bigger surprises of the week.
