The final frame of the afternoon session is over, and again it goes to the man with such a commanding advantage.

Mark Williams cannons into the blue to leave a red for Zhao Xintong, which drops, but the black – from the spot – doesn’t.

Luckily there’s nothing on for Williams and again, the Chinese man steps back up to build a 12-0 lead before turning down a risky pink.

Fouls from Williams turn that into a 22-0 lead. There’s then a tense exchange of safety shots as both players seek to avoid leaving an open table for the other.

Xintong improves to 37-0 before allowing Williams back up but a long red refuses to fall after a break of 16. So it’s another battle of safeties until the Welsh Potting Machine finds the middle.

A break of 20 moves him just one point behind Xintong but just as it seems he might reduce the deficit, a red finds the jaws and Xintong wraps up it 63-36.

That’s that until 7pm, when Xintong will need just one single frame to wrap this World Championship up.
