BBC SportTaylor Fritz ended his run of Grand Slam quarter-final disappointment by beating Alexander Zverev to reach the US Open semi-finals.
The American 12th seed had lost all four of his previous matches at this stage of a major but edged out 2020 runner-up Zverev 7-6 (7-2) 3-6 6-4 7-6 (7-3).
He roared in delight as Germany's Zverev pulled the final ball wide before holding his arms wide to take the acclaim of the crowd on Arthur Ashe Stadium.
The win keeps alive Fritz's bid to become the first American men's singles champion at Flushing Meadows since Andy Roddick in 2003.
Fritz could play another American in Frances Tiafoe for a place in a first Grand Slam final.
Tiafoe meets Bulgarian Grigor Dimitrov in Tuesday's night session in his quarter-final.
Fritz's victory followed New Yorker Emma Navarro beating Paula Badosa to reach the semi-finals of the women's singles.

Fritz 7-6 (7-2) 3-6 6-4 7-6 (7-3) Zverev
American Taylor Fritz speaking after reaching his first Grand Slam semi-final with victory over Alexander Zverev: "I feel amazing, I have had a lot of looks at quarter-finals over the last few years and today just felt different. I really felt like it was my time to go a step further, it's only fitting I'm doing it here on this court at the Open in front of this crowd."
On developing his game: "Having a big serve is helpful but at the top of the game, your serve comes back a little more. I've worked on adding so much to my game. My forehand and backhand have always been there but I've been trying to come to the net a bit, trying to mix in some drop shots, just trying to add stuff to the game so I can back up my serve a little bit better."
On facing Frances Tiafoe or Grigor Dimitrov in the semi-final: "I know the crowd would really want to see me play Frances so we get an American in the final. That could be crazy so I guess we'll see what happens but either way I'll be ready to go."

Fritz 7-6 (7-2) 3-6 6-4 7-6 (7-3) Zverev
For the first time in his career, and after losing his previous four Grand Slam quarter-finals, Taylor Fritz is into the semi-finals of a Slam.
He wins it three sets to one, edging the first and fourth sets via tie-breaks. Alexander Zverev, the world number four, his wait for his first Slam title goes on.
Emma Navarro moved into the semi-finals of the women's singles earlier today and what a great day it has been for the United States.
It could get even better with Frances Tiafoe taking on Grigor Dimitrov later on. The winner of that one meets Fritz in the semi-final.

Kim Clijsters
Four-time Grand Slam champion on BBC Radio 5 Sports Extra and BBC SoundsYou can feel the tension on both sides, it is basically the one who is able to keep the unforced errors down in these stages of the set and the match who will still have enough willpower to play aggressive tennis and really take it to their opponent.
