Sebastian Ofner enters US Open qualifying as the higher-ranked player at No. 127 but arrives with a dismal 2026 hard-court record and ongoing physical concerns, including heel and wrist issues that prompted recent withdrawals and limited his Davis Cup participation. The 30-year-old Austrian holds a 1-0 head-to-head edge after defeating Nishikori on hard courts in Miami in 2024, yet his recent losses in Toronto and Cincinnati qualifiers highlight inconsistent form. Kei Nishikori, the 36-year-old former world No. 4 and 2014 US Open finalist, returns via wildcard for what is expected to be his final professional season, bringing major-tournament pedigree and strong motivation despite a low ranking near 479 and sparse 2026 results. The hard-court surface and qualifying setting favor the veteran’s experience, while Ofner’s fitness and momentum remain key variables ahead of their August 25 opener.
