Alcaraz Stops Tiafoe's U.S. Open Run

Carlos Alcaraz & Frances Tiafoe engaged in a high-energy spectacle of a back-and-forth semifinal at the US Open, no point over when it seemed to be, no ball out of reach, no angle too audacious.

One sequence was so stuffed with "What?! How?!" moments by both men that Arthur Ashe Stadium spectators were on their feet before it was over & remained there, clapping, carousing.

Ultimately, enough of the winners went Alcaraz's way, and too many of the mistakes came from Tiafoe's racket.

And so it was Alcaraz who surged into his first Grand Slam final — and, in the process, gave himself a chance to become No. 1 at age 19 

by ending Tiafoe's run at Flushing Meadows with a 6-7 (6), 6-3, 6-1, 6-7 (5), 6-3 victory on Friday night.

"It was so electric. I mean, the tennis definitely matched the hype of the match."

"Unbelievable shot-making, gets, extending points, crazy shots ... at crazy times," Tiafoe said. "Yeah, I was getting riled up."
