Teenager Luke Littler made it through to the fourth round of the PDC World Darts Championship despite a below par performance against Ian White.
The 17-year-old won 4-1 but the scoreline does little justice to the scrap Littler endured to progress.
He survived set darts in the first - where he danced along with the Alexandra Palace crowd who were cheering for White - and fourth sets.
There were moments of brilliance from the fourth seed too, including needing just 39 darts to clean sweep the third set, where he averaged 115.
Littler, who was the pre-tournament favourite, showed an unusual outpouring of celebration when he claimed the fourth set too, before he won the fifth 3-1 to seal victory.
It took his average to 97.84 and above 54-year-old White, who said he used to beat Littler's grandad on the pub circuit in Runcorn in the 1990s in the build-up.
Littler will face unseeded Ryan Joyce, who he has never played before, in the fourth round on Monday.
"It was tough. Ian threw everything at me. If I hit a 180, he hit a 180 so I always had to stay switched on," Littler told Sky Sports.
"I wouldn't say there were nerves, it was a case of settling in quick.
"When you're 3-1 up going into the last break, you have that feeling that you're only three legs away and that's what I said to myself.
"I watched Ryan's game and he was very good. I've got to hit those doubles - 35% is not going to get me anywhere - but I know what's gone wrong."
