A spot in the next round is at stake on Tuesday, when Corentin Moutet goes up against Nick Kyrgios in the Stuttgart round of 32. Nick Kyrgios comes in at 3 wins from the last ten. Corentin Moutet is searching for form, having lost 5 in a row (3 of the last 10).

The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.

The serve is where this match separates: Kyrgios has been winning 76.4% of first-serve points to Moutet's 65.6%, and on grass that gap compounds fast. Moutet needs several things to break right at once; the percentages say they usually don't.
