A spot in the next round is at stake on Saturday, when Carlos Alcaraz goes up against Matteo Arnaldi in the Tokyo round of 16. Carlos Alcaraz comes in at 8 wins from the last ten. Matteo Arnaldi has won 4 of the last 10.

Carlos Alcaraz simply rates much higher on hard, and our number follows from it. Arnaldi needs several things to break right at once; the percentages say they usually don't.
