Matteo Arnaldi has had the better of this rivalry, winning 1 of 1 against Damir Dzumhur. On clay specifically it reads 1-0 Arnaldi — worth more than the overall number this week.
The serve is where this match separates: Arnaldi has been winning 70.4% of first-serve points to Dzumhur's 65.4%, and on clay that gap compounds fast. Arnaldi should have enough here, though Dzumhur has the tools to make the scoreboard uncomfortable.
