Matteo Arnaldi and Stefanos Tsitsipas meet in the round of 64 at French Open on Thursday. Stefanos Tsitsipas has won 5 of the last 10. Matteo Arnaldi is rolling — 6 straight wins, 8 of 10 in recent play.
Nothing separates them historically — the head-to-head sits at 1-1. On clay they're dead even at 1-1 — worth more than the overall number this week.
The serve is where this match separates: Tsitsipas has been winning 74.8% of first-serve points to Arnaldi's 69.7%, and on clay that gap compounds fast. Arnaldi needs several things to break right at once; the percentages say they usually don't.
