Madison Keys enters the US Open third-round matchup as the consensus favorite, reflecting her higher ranking, Grand Slam experience, and home-crowd support on hard courts. The American recently saved five match points to advance past Anna Bondar in a grueling three-setter and reached the Cincinnati quarterfinals, signaling improved resilience after earlier 2026 inconsistencies. Qinwen Zheng, a former world No. 4 and Olympic champion returning from elbow surgery, has battled through qualifying and three consecutive three-set wins, including against Yulia Putintseva. Their head-to-head stands at 1-1, with Zheng prevailing in their most recent encounter in Miami. Both players have shown vulnerability in extended matches, increasing the likelihood of a competitive, potentially deciding-set battle on the Grandstand.
