Zhang earned her spot with a confident 6-4, 6-3 straight-sets victory over Eva Lys in the first round, snapping a six-match losing streak dating back to Merida. As the No. 17 seed and world No. 17, Keys entered as the heavy trader favorite thanks to her power baseline game and higher ranking, despite Zhang holding a 5-3 head-to-head edge, mostly on faster surfaces; clay histories are limited for both, with no major recent shifts beyond the illness.",
