Anna Kalinskaya and Camila Osorio meet in the round of 32 at French Open on Saturday. Anna Kalinskaya is rolling — 5 straight wins, 7 of 10 in recent play. Camila Osorio has won 3 in a row and 7 of the last 10 overall.

Nothing separates them historically — the head-to-head sits at 2-2. On clay specifically it reads 1-0 Kalinskaya — worth more than the overall number this week.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. Little separates them; Kalinskaya gets the nod on the finest of margins.
