A spot in the next round is at stake on Friday, when Elina Svitolina goes up against Polina Kudermetova in the Washington round of 16. Elina Svitolina has won 7 of the last 10. Polina Kudermetova has dropped 3 straight and sits at 5-5 over the last ten.

Elina Svitolina simply rates much higher on hard, and our number follows from it. Kudermetova comes in off a compressed schedule. The edge belongs to Svitolina — real, but not the kind you take for granted at this level.
