Which Argentine beat Steffi Graf in the 1990 US Open women's singles final?

Gabriela Sabatini defeated Steffi Graf in the 1990 US Open women's singles final.

Sabatini won 6–2, 7–6, earning the first and only major singles title of her career. Graf entered the match as the two-time defending champion, but Sabatini controlled the opening set and then held her nerve in a tight second-set tiebreak.

The final was part of a significant rivalry between the Argentine and German stars. It was a rematch of the 1988 US Open final, which Graf won, and Sabatini had also lost to Graf in the 1989 US Open semifinals. Their 1990 meeting therefore gave Sabatini a breakthrough victory on one of tennis's biggest stages.

Sabatini is sometimes confused with other Argentine players because several prominent women represented Argentina internationally. Mercedes Paz, Paola Suárez, and Gisela Dulko all had notable careers, but none defeated Graf in that final. Sabatini's New York triumph remained her lone Grand Slam singles championship.
