Player profile
Yeonwoo Ku used four 2025 titles to jump into the Top 200
Yeonwoo Ku won her first ITF singles title at home in Yeongwol in 2019 and added two more trophies in 2021. She qualified for the 2023 Korea Open at No. 540 to make her WTA singles debut, but her largest ranking move came two years later. Ku won four ITF hard-court titles in 2025, at Taipei, Nakhon Pathom, Lagos and Loule, and rose from outside the Top 400 into the Top 200. She finished that season with runner-up appearances at the Takasaki W100 and Yokohama W50. Those results turned a career previously centered on smaller events into a credible Grand Slam qualifying campaign.

US Open story
Yeonwoo Ku begins a first chase for the US Open main draw
The official tournament and WTA records list no previous US Open women's singles main-draw appearance for Ku. Her 2026 qualifying opener is against Astra Sharma, an experienced Australian who has already competed regularly at tour level. Ku must win three matches to reach the main field, so even a first-round victory would leave two more qualifying steps. The surface suits her recent development: every one of her four 2025 singles titles and both late-season finals came on hard courts. New York provides a higher-pressure version of the same conditions that carried her ranking into major-qualifying range.
What to watch
Yeonwoo Ku versus Astra Sharma measures a hard-court rise
Ku's 2025 record shows repetition rather than one isolated week. She won titles in four different cities and then pushed Himeno Sakatsume to three sets in the Takasaki W100 final before reaching another final in Yokohama. Against Sharma, that match volume should help Ku trust her hard-court timing, but the Australian's tour experience raises the standard of serve and return she must handle. Fans should watch whether Ku can hold baseline position after the return and avoid giving away the next ball. Her recent rise was built on winning complete tournament weeks; US Open qualifying asks her to restart that process against a more seasoned opening opponent.
