Claire Liu defeated Ella Seidel 4–6, 6–0, 6–4 in the quarter-final of the WTA 250 Guangzhou event on hard court, upsetting the pre-match favourite despite Seidel's superior odds of 1.4 to Liu's 2.9. After losing the opening set, Liu recovered decisively to claim the next two frames with commanding tennis, particularly in the second set where she conceded no games. The American's ability to reset after an early setback proved decisive in securing a place in the semi-finals. Liu's comeback victory demonstrates improved mental resilience and positions her well for the remainder of the tournament.
