Josh Rock was perfect in that leg, but this is the problem when you throw second!”The pundit added: “That is the second best leg you’ll ever see in your life,” in reference to Michael Smith’s effort against Michael van Gerwen in the 2023 World Championship final.On that occasion, Van Gerwen threw eight perfect darts before missing at double, only for Smith to complete his own nine-darter during the same leg.Littler could be seen applauding the crowd in response, with Rock himself looking on in disbelief.The Northern Irishman appeared to celebrate his opponent’s heroics by clapping, before the pair embraced on stage in a classy show of respect.It was the first nine-dart finish of this year’s World Matchplay and the tenth in the event’s history. Dimitri Van den Bergh was the last player to do so in the first round in 2024 against Martin Schindler.Littler had trailed 6-1 prior to his perfect leg, which went on to inspire a dramatic turnaround.He won 15 of the remaining 23 legs to claim a 17-14 victory over Rock.Speaking afterwards on his nine-darter, Littler admitted: “It definitely sparked me into life. I didn’t want to give it big [one].“I was playing awful. At that point I wanted to go into the break at 6-, but I ended up 7-3 down.“Once again I said to myself, ‘I could do it and come back again.'”GettyLittler will become the youngest ever Triple Crown winner if he beats Wade on Sunday[/caption]Despite his humble attitude, he had made World Matchplay history alongside Rock.The pair’s combined 29 180s is the most in a single match at the tournament.How many nine-darters does Littler have?Littler’s perfect leg on Saturday was the fourth televised nine-darter of the 18-year-old’s career.His first came at the Bahrain Darts Masters against Nathan Aspinall in January last year.Meanwhile, he has repeated the feat against Luke Humphries and Van Gerwen in the Premier League in 2024 and 2025.The latter came with a new route as Littler ditched the triple 20, triple 19, double 12 finish he had used for the previous two.GettyLittler has already beaten upcoming opponent Wade in the UK Open final earlier this year[/caption]Instead, he checked out 141 with triple 20, triple 17 and double 15, the same approach as his nine-dart finish against Rock.Following his previous perfect leg in March, Littler revealed he plans to use the new route when possible for the rest of the year.He explained: “I didn’t even realise the double 15 was in until Huw (Ware, referee) shouted it. So I think that’s the new route to go for this year.“You’ve seen players in the world championships hit the nine and go out in that game, so I had to focus after that.“Michael won the next two legs but I managed to get back into it. It’s good to pick up another nightly win, more crucial points, and to have a six-point over Luke (Humphries) is a good boost for myself.”
