Which player became the first Canadian to win a major singles title at the 2019 US Open?

Bianca Andreescu became the first Canadian to win a major singles title at the 2019 US Open.

Andreescu defeated Serena Williams 6–3, 7–5 in the final at the USTA Billie Jean King National Tennis Center in New York. The victory was Andreescu’s first Grand Slam title and came in only her fourth major main-draw appearance.

The achievement is sometimes confused with Canada’s earlier success in doubles. Canadian players had won major doubles titles before 2019, but Andreescu was the first Canadian—man or woman—to win a major singles championship. She was also the first player born in the 2000s to win a major singles title.

Her victory had extra historical weight because it came against Williams, who was seeking a record-equalling 24th major singles title. Andreescu had also won the Canadian Open shortly before the US Open, making her the first woman since 2000 to win both events in the same season.
