A spot in the next round is at stake on Friday, when Katerina Siniakova goes up against Maria Timofeeva in the Cincinnati first round. Katerina Siniakova comes in at 4 wins from the last ten. Maria Timofeeva has won 7 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. Siniakova should have enough here, though Timofeeva has the tools to make the scoreboard uncomfortable.
