Frances Tiafoe
On September 5, 2022, in the fourth round of the US Open on Arthur Ashe Stadium, 22nd seed Frances Tiafoe beat 22-time Grand Slam champion Rafael Nadal 6–4, 4–6, 6–4, 6–3, ending Nadal's 22-match Grand Slam winning streak and reaching his first US Open quarterfinal. Tiafoe is the son of immigrants from Sierra Leone: his father, Constant "Frances Sr." Tiafoe, helped build the Junior Tennis Champions Center in College Park, Maryland, then worked there as custodian, converting a spare office into a bedroom where Frances and his twin brother, Franklin, slept many nights while their mother, Alphina Kamara, worked overnight nursing shifts. The boy learned the game inside the building his father cleaned. "I'm a son of immigrants," he said at the tournament. Two days after beating Nadal, he defeated Andrey Rublev to become the first Black American man in a US Open singles semifinal since Arthur Ashe in 1972.
