Carlos Alcaraz ends Frances Tiafoe's dream run at US Open after epic battle to enter final

Spanish teenager Carlos Alcaraz ended Frances Tiafoe's amazing run at the US Open with a 6-7(6), 6-3, 6-1, 6-7(5), 6-3 win to reach his first major final, where he will face Casper Ruud with the world number one ranking on the line.

Despite playing into the early morning hours in his previous two five-set matches, Alcaraz no signs of fatigue on Friday. He fell on his back and covered his face with his hands after winning the hard-fought battle.

The 19-year-old Spaniard became the youngest men's Grand Slam finalist since compatriot Rafael Nadal captured the first of his 22 Slams at the 2005 French Open.

Norway's seventh-ranked Ruud earlier defeated Russia's Karen Khachanov 7-6 (7/5), 6-2, 5-7, 6-2 to also reach his first Grand Slam final.

Tiafoe, however, went down fighting by saving three match points and retrieving breaks in both of the last two sets.

"We are in the semi-final of a Grand Slam, we have to give everything we have inside, we have to fight until the last ball," said Alcaraz.

"It doesn't matter if you're fighting for five hours or six hours. It doesn't matter, you have to give everything on court."

WHAT A TOURNAMENT. Congratulations @FTiafoe - You were sensational⚡️
