Karolina Muchova has reached the US Open semifinals for the second consecutive year after defeating Beatriz Haddad Maia 6-1, 6-4. Despite dealing with illness and hip discomfort, Muchova dominated the match and has yet to drop a set in the tournament. Following a 10-month hiatus due to wrist surgery, Muchova returned to competitive play in June and has made a remarkable comeback. She will face either world number one Iga Swiatek or American Jessica Pegula in the semifinals. Muchova's victory over Haddad Maia included multiple medical breaks, but she managed to maintain her form and finish strong. Haddad Maia also faced her own challenges, calling for medical assistance during the match.
