The lights went out, in the first frame of Ronnie O’Sullivan’s Welsh Open semi-final against Joe Perry on Saturday night causing a 15-minute delay.
It did not upset Ronnie’s rhythm though. He went on to defeat Perry 6-3 to progress to the final against Neil Robertson.
In the third frame O’Sullivan rattled off a break of 124. On the way, he pulled off an audacious plant which drew huge applause from the crowd, which you can see below.
