Stefan Kozlov and Noah Rubin will play in the first all-US boys’ final at Wimbledon since 1977.

The sixth-seeded Kozlov beat eighth-seeded Johan Sebastien Tatlot of France 6-3 7-6 (9-7) in the semi-finals on Saturday, while Rubin defeated another American, Taylor Harry Fritz, 6-4 6-2.

The previous time two United States boys met in the junior final at Wimbledon was 1977, when Van Winitsky beat Eliot Teltscher.

Either Kozlov or Rubin will be the first American to win the title since Donald Young in 2007.

In the girls’ final, Kristina Schmiedlova of Slovakia will face Jelena Ostapenko of Latvia.

Both junior finals are scheduled for Sunday.
