Si Jiahui produced a dominant display to extend his lead over Luca Brecel to 11-5 in the World Championship semi-final in Sheffield.
Leading 5-3 overnight, the Chinese qualifier took control with breaks of 52, 89, 58 and a wonderful 122 as he won four of the first five frames.
A stunned Brecel made just one half-century break as he struggled.
And Si, 20, who could become the youngest Crucible finalist, rounded off the session with runs of 55 and 71.
