A spot in the next round is at stake on Wednesday, when Karen Khachanov goes up against Ugo Humbert in the Hamburg round of 16. Karen Khachanov comes in at 5 wins from the last ten. Ugo Humbert comes in at 6 wins from the last ten.
Ugo Humbert has had the better of this rivalry, winning 2 of 3 against Karen Khachanov. On clay specifically it reads 1-0 Humbert — worth more than the overall number this week.
Karen Khachanov simply rates much higher on clay, and our number follows from it. The edge belongs to Khachanov — real, but not the kind you take for granted at this level.
