A spot in the next round is at stake on Thursday, when Clara Tauson goes up against Ekaterina Alexandrova in the Monterrey round of 16. Ekaterina Alexandrova is 6-4 across recent matches. Clara Tauson is 3-7 across recent matches.
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 Alexandrova fractionally more likely to land the big points.
