Mark Williams has been confirmed as the final entrant for the 2026 British Seniors Open in Derby, joining Ronnie O’Sullivan in a high-profile lineup for the event held from December 27-28.
The 51-year-old Welshman rounds out an eight-player field at the Vaillant Live, bringing current main-tour competitiveness to the exhibition.
Williams Competes Against O’Sullivan's Senior Tour Experience
- Competitive Edge: Williams enters the field with recent form, having reached the English Open final earlier this season, making him a primary contender against the seniors-tour specialists.
- O’Sullivan’s Status: Despite losing 4-0 to Shaun Murphy in the first round of the Champion of Champions, O’Sullivan remains the reigning World Seniors Championship winner.
The Welshman Joins a Star-Studded Field
Adding Williams to the British Seniors Open roster increases the tournament's profile. According to SnookerHQ.com, the Welsh veteran completes a list of participants that includes reigning World Seniors champion Ronnie O’Sullivan, defending tournament winner Joe Perry, and multi-time world senior champion Jimmy White.
Williams remains a potent force on the professional main tour, a rarity for many in the seniors circuit. His recent run to the English Open final, where he lost to Ali Carter, showed he can still play at a high level at 51.
| Player | Key Status / Recent Form |
|---|---|
| Ronnie O’Sullivan | Reigning World Seniors Champion |
| Mark Williams | 2026 English Open Finalist |
| Joe Perry | Defending British Seniors Open Champion |
| Jimmy White | Most successful player in Seniors Tour history |
O’Sullivan Returns to Derby Roots
The seven-time world champion expressed enthusiasm for the venue, noting the historical significance of the location to his early career trajectory.
“Derby was always an annual visit on the tour when I was first playing, and the Assembly Rooms was a great venue – Vaillant Live looks even better!” said O’Sullivan. He will arrive in Derbyshire looking to build on his May victory at the World Seniors Championship, where he defeated Joe Perry in the final.
Star Names Drive Commercial Growth and Broadcast Viewership
The British Seniors Open has seen strong interest, with World Seniors Snooker chairman Jason Francis highlighting the involvement of star names like O’Sullivan and Williams. World Seniors Snooker chairman Jason Francis emphasized the commercial impact of the event’s growth, citing last year’s broadcast performance of over 4 million viewers on Channel 5 as a benchmark.
“Last year was the return of snooker to the city and look how Derby welcomed us in person and over 4 million watched on Channel 5,” said Francis. The tournament is scheduled to return to the same network for the 2026 edition, ensuring broad UK and Ireland access.
The field is rounded out by Ken Doherty, Reanne Evans, and Stephen Maguire, all of whom add tactical depth to the draw. The competition will conclude on December 28, following the two-day stint at the Vaillant Live venue.
