Karolína Muchová defeated Linda Nosková 6-7 6-4 6-2 in the first round of the US Open on hard court, confirming her status as the slight pre-match favourite. The Czech player recovered from a tight opening set that went to a tiebreak, then took control in the second and third sets to advance comfortably. Nosková, competing in the same tournament, could not maintain the intensity required to trouble Muchová over the full match distance. The result keeps Muchová on track in the draw and demonstrates her ability to convert tight early contests into victories.
