A spot in the next round is at stake on Thursday, when Alex Rybakov goes up against Gabriel Debru in the Fort Worth (Usa) round of 16. Gabriel Debru comes in at 5 wins from the last ten. Alex Rybakov 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 Debru fractionally more likely to land the big points.
