Cincinnati Open 2026 Day 6 Preview
Day 6 at the Cincinnati Open brings an massive 42-match schedule across singles and doubles. The stakes are higher than ever at the Lindner Family Tennis Center, highlighted by defending champion Iga Swiatek, a fierce battle for the WTA World No. 1 ranking, and a deep roster of American favorites taking to the courts.
Here are the key storylines and matches to watch on Sunday.
1. Toronto Champions Pivot to Cincinnati
Fresh off winning the WTA 1000 trophy in Toronto, Iga Swiatek begins her title defense in Cincinnati. The six-time Grand Slam champion won the Rookwood Cup last year with a hard-fought victory over Jasmine Paolini. Following a first-round bye, the 7th seed opens on P&G Stadium Court against Colombian qualifier Emiliana Arango, who impressed on Friday by defeating legend Venus Williams in straight sets.
On the men’s side, back-to-back Canadian Open champion Ben Shelton headlines the night session on P&G Stadium Court (not before 7:00 PM). The 8th seed takes on Portuguese qualifier Jaime Faria in their first-time meeting. Shelton enters Ohio on a roll after becoming just the fourth man this century to successfully defend his Canadian Open title.
2. World No. 1 Ranking on the Line
The battle for the top spot in women’s tennis takes center stage on Sunday, with Aryna Sabalenka and Elena Rybakina both in action.
- Aryna Sabalenka (1): The 2024 Cincinnati champion has held the No. 1 ranking for 96 consecutive weeks. She begins her campaign on Grandstand (not before 3:00 PM) against Australia’s Talia Gibson.
- Elena Rybakina (2): Toronto finalist Rybakina is right behind Sabalenka in the standings and could claim the top spot with a deep run. She kicks off the day session on P&G Stadium Court (11:00 AM) against American fan favorite Taylor Townsend.
3. Brazilian Sensation Joao Fonseca on Court 3
Nineteen-year-old Joao Fonseca returns to action on Tony Trabert Stadium 3 against Dutchman Botic van de Zandschulp. The pair have split their previous two meetings, with Fonseca winning at the 2024 Davis Cup and Van de Zandschulp taking their 2025 match in Brussels. Coming off his first Grand Slam quarterfinal run at Roland Garros in June, Fonseca will have plenty of support from the crowd.
4. Heavyweight American Lineup Across All Courts
American tennis fans have a packed schedule to follow on Day 6, featuring former champions, top seeds, and rising talent:
