Overview
- USTA officials confirmed Jannik Sinner’s illness-related withdrawal from the US Open mixed event, and organizers replaced his team with Americans Danielle Collins and Christian Harrison to face Alexander Zverev and Belinda Bencic.
- Carlos Alcaraz won the Cincinnati Masters final after Sinner retired at 0–5 roughly 22–23 minutes in, securing his 22nd tour title and trimming the rankings gap to the world No. 1.
- Alcaraz and Iga Swiatek traveled directly to New York to play the mixed showcase, with Alcaraz praising the concept even as he acknowledged the tight turnaround.
- The overhauled mixed format runs Aug. 19–20 before the main draw, uses shortened sets with no‑ad scoring and a match tiebreak, and allocates many places by singles ranking and wildcards, limiting spots for doubles specialists.
- Recent heat and a dense schedule have raised fitness concerns after visible struggles from Sinner and Zverev in Cincinnati, and Sinner says he will contest the US Open singles if he feels physically and mentally ready.
