Men's Singles Final and Champion
Rafael Nadal defeated Daniil Medvedev in the 2019 US Open men's singles final with a score of 7–5, 6–3, 5–7, 4–6, 6–4. It was his fourth US Open title and 19th major singles title overall, extending his lead at the time of the event. The match took place on September 8, 2019, at the USTA Billie Jean King National Tennis Center in New York City. Medvedev, ranked 5th entering the tournament, reached his first major final at age 24. Nadal's victory marked his third consecutive major final win after the French Open and Wimbledon earlier that season.
The men's singles champion received a prize of $3.85 million, while runner-up Medvedev earned $1.85 million. The total prize pool for the 2019 US Open exceeded $57 million, setting a record at the time. Nadal's win helped him maintain the ATP No. 1 ranking for the remainder of the season. The tournament featured multiple top-10 upsets, including losses by Alexander Zverev and Stefanos Tsitsipas before the semifinals. Medvedev's serve and baseline play tested Nadal in the final, particularly on the hard courts of Arthur Ashe Stadium.
Women's Singles Final and Champion
Bianca Andreescu defeated Serena Williams in the 2019 US Open women's singles final with a score of 6–3, 7–5. Andreescu, ranked 152nd before the tournament, became the first Canadian player to win a singles major in the Open Era. The match took place on September 7, 2019, on the same final day as the men's event. Williams, competing for her 24th major singles title, was attempting to equal Margaret Court's all-time record. Andreescu's victory made her the first wildcard champion in US Open history and the first teenager to win the title since 2004.
Andreescu's run included wins over top seeds Karolína Plíšková and Elina Svitolina before facing Williams in the final. She saved match points in the semifinal against Belinda Bencic, winning 7–6, 5–7, 6–4. The women's singles champion received $3.85 million, identical to the men's winner, reflecting the US Open's equal prize money policy. The 2019 tournament marked the first time both major singles champions were ranked outside the top 10 at the time of their final victories. Andreescu's victory generated significant global media coverage and boosted her ranking to No. 5 within weeks.
