Ronnie O’Sullivan v Judd Trump LIVE: Snooker updates as stars clash in Saudi semi-final

O’Sullivan breaks off in the third frame but Trump lands a long pot to sink the opening red. He misfires off the brown in the follow up and gives O’Sullivan a chance.

He’s on a red to the bottom right.

This is a tight frame still. Trump, with a lead of 13, can’t get over the line and decides to play safe. O’Sullivan leaves the green on and Trump rolls it home before nestling in the brown too.

He was made to work for it by O’Sullivan who played some fine shots off the back foot but Trump tidies up the table and draws level in the match.

Trump manages to snooker O’Sullivan as a bunch of reds are knocked over to the left side of the table. Trump comes down the cushion and gets it to land.

This is a tough table to clean up but he fancy taking the frame from here.

Another tense frame developing here. O’Sullivan takes 36 point lead before a couple mistakes from both players sees safety shots pulled out.

Trump slowly gets 12 points on the board but leaves nothing on for O’Sullivan to go at.

Judd Trump will be annoyed about that frame. He was twice in control of it and twice let things slip away from him. Ronnie O’Sullivan took advantage and will hope to continue that as the match goes go.

Trump breaks off for the second frame.

With a lead of 50, Trump errs and lets O’Sullivan back into the contest here. He slots in three of the remaining reds and has strong positional play for the remaining balls.

In no time the break moves to 22 and when the black drops, followed by the remaining red O’Sullivan is 20 behind with all the colours remaining.

He pots and plays off the black to set up the yellow. The drops too, then the green and the brown. As the blue falls into the middle left pocket, O’Sullivan takes the lead and holds it by cleaning up the pink and the black.

He wins the frame 72-58 and goes ahead in the match. That break was 64 and O’Sullivan strikes first.

After a shaky start to the frame, Trump settles down and works his way around the table with a finely tuned break off 33 to take him above 50.

He leads by 45 with 67 remaining on the table.

Mistake! Trump leaves a routine red over the pocket which brings O’Sullivan onto the table trailing by 20 points. Can he take advantage from here?

No! O’Sullivan bobbles a red out of the pocket trying to smash open the rest of the pack. His break ends at 8.

That is naughty from Trump. He slips a red in from the middle of the table and follows up with the black to get this break started in perfect fashion.

A fine slice to the bottom left pocket sees a second red drop but he’s forced to bail out on the blue and the golden ball is removed from the table.

This could be a big break from Trump now.

O’Sullivan breaks off first and skims the bottom red before leaving the ball safe near the top cushion. Trump fancies taking on a long pot but skirts both sides of the bottom left cushion yet leaves nothing on for the Rocket.

Interesting start to this one.
