St Helens get a penalty inside their own half and Luke Walsh kicks to halfway. The set of six takes them to within sight of the Leeds line but Zak Hardaker mops up any danger.
Meanwhile, Leeds have brought Jamie Peacock off the bench.

BBC Radio MerseysideQuote MessageIt’s a magnificent try from Roby, the St Helens fans are leaping in the air. From 35 metres out he left like a greyhound from the blocks, beats man after man and shrugged a couple of tackles off and scored at the side of the posts. Wonderful try.

That James Roby try came after a superb start by Leeds. The Rhinos' momentum has been well and truly squashed.

Leeds Rhinos 0-6 St Helens
That is astonishing by James Roby! St Helens strike first, with their first attack, and it's a moment of magic from the England hooker.
Roby takes off from dummy half and bursts through what seems like a million Leeds tackles before touching down near the posts.
One of the tries of the season. Sensational.

Leeds definitely on the front foot in the opening moments at Headingley. This time it's full-back Adam Quinlan who catches a high Danny McGuire kick.
But Saints are soon retreating again as Mose Masoe's offload is knocked on and Leeds have a scrum just inside the visitors' half.
One tackle and one ball spill by Kallum Watkins later, Saints have the ball back.

Leeds go through their set but St Helens survive, as Adam Swift catches a high bomb out wide.
Amazing how one great catch can settle a lot of nerves.

We're under way with a mighty boot forward by Leeds.
And a knock-on by Jordan Turner! He fails to grasp the kick and Leeds have the ball in a promising position straight away.

St Helens, in Keiron Cunningham's first season as head coach, are one win away from a second successive Grand Final appearance.

"I want my last game at Headingley to be a win, so I'm focusing on the win and the emotion will come afterwards," Peacock told BBC Radio Leeds.
"It's do or die. My career's over if we lose, and we get to go to Old Trafford if we win. I don't think the stakes get any higher."

Brian Noble asks if that last-minute try against Huddersfield last week to secure the League Leaders' Shield was the emotional limit of Leeds Rhinos.
I guess we're about to find out...
