Judd Trump leads world champion Ronnie O'Sullivan 5-3 at the end of a tense afternoon session in the Northern Ireland Open final in Milton Keynes.

Trump has been playing some fine snooker in the highly-anticipated clash between two greats of the sport.

The session began with a poor safety from O'Sullivan, gifting Trump the opportunity to jab in a long blue into the yellow pocket. The reigning champion then pocketed the pink to secure a cagey first frame.

A bizarre second frame saw O'Sullivan elect to give Trump a second run at swerving the cue ball around the black to pot a red hanging over the pocket, with the two-time defending champion obliging, before the Rocket played on despite needing six snookers.

With the session seemingly slipping away, O'Sullivan produced a sensational fluke in the third which finally got the 44-year-old on the scoreboard. He missed a green to the bottom left by a mile, but watched it go off four cushions and then drop into the left middle before he added the brown, and a difficult cut on a blue.

Trump took a 3-1 lead with a break of 69 before returning after the interval to pocket a crucial pink and deepen O'Sullivan's problems in the fifth.

O'Sullivan desperately needed the sixth and he dug deep as he pocketed a brilliant red to keep him within touching distance, but Trump restored his three-frame advantage in style with a clinical break of 128.

The Rocket finished up by reducing the arrears to two with a 137 clearance - his sixth century of the tournament and a much-needed break heading into Sunday's evening session.
