Viewers of the Lakeside World Championship were left gobsmacked when a darts commentator shared an explicit comment made by a former world champion. The revelation came on the opening day of the tournament, during a match between Vince Tipple and Haruki Muramatsu.

In the first set, commentator Andrew Sinclair began discussing the significance of averages before revealing the rather forthright views of three-time BDO world champion Martin Adams on the subject.

Sinclair, who is also a player, said: "We spoke about averages earlier. I remember a conversation with Mr Martin Adams, a legend on this stage, many years ago."

Choosing not to censor Adams' choice of words, he continued: "To pardon my French, I was talking to him about averages, and he said, 'Let me be frank, Andrew, son, averages aren't worth a w***. So, I've tried to take that on board, particularly with regards to my own performances."

The comment was aired live on the tournament's YouTube stream. Adams' opinion certainly holds some clout, given Adams' legendary status in the BDO (now WDF) system, having won the Lakeside title in 2007, 2010 and 2011.

Viewers were more taken aback by Sinclair's language, although many found it hilarious. One called it a "highlight" of the night, posting: "With most people (rightly) complaining about the horrendous camerawork ruining their enjoyment of the WDF World Championships, we were treated to one unexpected highlight. Step up, Andrew Sinclair."

Another added: "Andrew Sinclair: Legendary darts commentary." A third demanded: "Andrew Sinclair should be co-comms on all WDF comps. He's good and knowledgeable and not shouty or irreverent or juvenile like some people/kids they use on streams. Another joked: "He went full Partridge. " And a fifth quipped: "F****** hell, you don't get that on Sky Sports."

The WDF World Championship features a field of 48 men, 24 women, eight boys and four girls battling for their respective crowns, with a total prize pot of £221,000.

It's a stark contrast to the PDC World Championship, where the prize money has ballooned to an eye-watering £5million, with £1million awarded to the champion.

Shane McGuirk holds the men's title after beating Singapore legend Paul Lim 6-3 in last year's showpiece to secure his first Lakeside title.

Three-time women's champion, Beau Greaves, won't be defending her title after choosing to compete at the PDC Worlds, which begins on December 11, instead. PDC regulations prohibit players from participating in both tournaments.
