A spot in the next round is at stake on Friday, when Peyton Stearns goes up against Viktorija Golubic in the Beijing round of 64. Peyton Stearns has won 5 of the last 10. Viktorija Golubic has won 5 of the last 10.

Neither the serve numbers nor the ratings separate these two by much, which is why our number stays close to even. A tiebreak or two would surprise nobody, with Stearns fractionally more likely to land the big points.
