Elena Rybakina, the world No. 2 and two-time Grand Slam champion, enters her US Open first-round match against 17-year-old American Thea Frodin (WTA ~580) as the overwhelming favorite on hard courts. Rybakina posted a strong 2026 season with an Australian Open title and deep runs in Toronto and Cincinnati before retiring injured in the latter against Iga Swiatek. She has not practiced since the leg issue but reports steady recovery and has avoided a serious diagnosis. Frodin, primarily a junior and ITF competitor with limited senior experience, faces a steep step up in class with no prior head-to-head history. The match timing and Rybakina’s health remain the key variables.
