Danielle Collins and Christian Harrison will replace Sinner and Katerina Siniakova, taking on Belinda Bencic and Alexander Zverev in the first round. This change comes after Sinner retired from the Cincinnati Open final against Carlos Alcaraz, citing health issues.

About the New Partnership:

Danielle Collins: A former Grand Slam finalist, Collins brings her singles expertise to the mixed doubles event. She's a popular player on tour and will look to make the most of this opportunity.

Christian Harrison: A doubles specialist, Harrison has experience in the US Open mixed doubles event, having reached the semifinals previously. He's won two ATP doubles titles in 2025 with Evan King.

The US Open's mixed doubles competition has generated buzz with its new format, featuring 16 teams and a two-day event. Despite some controversy surrounding Siniakova's exclusion, Collins and Harrison are set to face off against Bencic and Zverev in an exciting first-round match.

Jannik Sinner, the reigning champion of the Australian Open, Wimbledon, and US Open, struggled in the sweltering heat at the Cincinnati Open on Monday. He retired from his match after falling behind 5-0 in the first set, looking uncomfortable throughout. This unexpected setback might raise concerns about his preparation for the upcoming US Open.

Sinner's performance in Cincinnati might not be a cause for concern, considering his impressive record in Grand Slam tournaments. In the 2024 US Open, he defeated Taylor Fritz 6-3, 6-4, 7-5 to claim the men's singles championship.
