On the other end, there was Carlos Alcaraz, the rising Spanish sensations who has been phenomenal during the tournament. One of these incredible stories unfortunately had to end today.

It was a hard-fought battle, but in the end, it was Carlos Alcaraz that prevailed, beating Frances Tiafoe in a grueling five-set match. The Spaniard punched his ticket to the US Open grand finals. Along the way, Alcaraz made history, becoming only the second teenager to make it to the finals in Queens.
