Danielle Collins missed out on a chance to win her maiden Grand Slam title in the new-look US Open mixed doubles event.
Partnering with Christian Harrison, Collins entered the US Open mixed doubles tournament as a last-minute replacement for Jannik Sinner and Katerina Siniakova.
Immediately finding success, the pair won their opening two matches in straight sets, against Alexander Zverev/Belinda Bencic and Ben Shelton/Taylor Townsend.
Advancing to the semifinals, Collins and Harrison took on the defending US Open mixed doubles champions, Andrea Vavassori and Sara Errani.

Unfortunately for the Americans, they failed in their bid to reach the final, losing 2-4, 2-4 on Arthur Ashe Stadium.
Looking ahead to the singles tournament, Collins confirmed how she plans to recover during her post-match press conference.
Danielle Collins is going to ‘put her feet up’ before the US Open and manage her back injury
Speaking to the media after her and Harrison’s semifinal defeat, Collins outlined what she intends to do over the next few days before the singles event begins.
“I’m going to need like a day or two off for sure. After my back injury in Cincinnati, I actually only had one practice. I had nine days off. I came into the tournament a little bit cold turkey,” she said.
“You know what, I played better. I actually thought I played better.
“I was joking with my coach, maybe I just need to practice less because I feel like the more I play, the worse I get. Maybe less is more for me. I’m serious. Sometimes you play too much and you get worse, especially at this age now.
“I’m going to get the feet popped up on the couch, yeah, just kind of chill out with Quincy for the next couple of days. Yeah, maybe throw a few practices in there, right, here and there, try to get my back right for the tournament.”

Collins explained how her back is still affecting her after struggling with an injury at the Cincinnati Open.
“I’ve still been managing this injury. Obviously, people can probably tell with the way I was serving a little bit,” she said.
“A lot of 70-mile-an-hour serves. Not my biggest serving experience.
“But it was tricky. It was super tricky. I’m full of tricks, so it worked.”
Collins was in tears during her first-round match in Cincinnati, shouting, ‘Why is this happening to me?’ to her team.
After the match, she took to social media to explain why she was in such discomfort, revealing the injury she is suffering from.
“Anyone who has a herniated disc knows my pain,” said Collins.
Looking to recover fully from the injury, Collins will finish her 2025 season in New York, eyeing a full return to the WTA Tour in January 2026.
Has Danielle Collins’ 2025 season been a success?
After deciding against retirement for personal reasons in 2024, Collins was hoping to achieve big things in 2025.
She began her year with a title, supporting from the sidelines as Team USA won the United Cup, defeating Poland in the final.

Collins was, however, unable to add to her trophy tally on the WTA Tour, enjoying her best tournament in Strasbourg, where she reached the semifinals.

That’s not to say she didn’t pick up some big wins along the way, as Collins secured a stunning victory against the world number two in Rome.
Taking on the Polish Grand Slam winner, Collins dominated Swiatek 6-1, 7-5, to book her place in the fourth round of the Italian Open.
She’ll certainly be looking to pick up some more big wins at the US Open, her final event of the year.
The 2025 US Open women’s singles tournament is scheduled to begin on Sunday, August 24.
