Men's tennis world number one Novak Djokovic and Daniil Medvedev are about to face off in the U.S. Open final.
Djokovic is looking for the first calendar-year Grand Slam since Steffi Graf in 1988 and the first on the men's side since Rod Laver in 1969.
He's also hoping to break the men's Grand Slam singles title record with his 21st win.
Medvedev is looking for his first major title. He's made the finals twice before, and lost to Djokovic in this year's Australian Open.
