St Helens took a four-point lead at the top of Super League, as they beat Wigan Warriors 10-36, with Regan Grace scoring a hat-trick.
Unlike the Hull Derby previous, it was the away side who got themselves on the scoreboard first.
James Roby burrowed his way over from the play-the-ball to score in his 47th appearance against the Warriors.
The Saints then suffered a major blow, as Mark Percival left the field with a hamstring injury, as Louie McCarthy-Scarsbrook filled in at centre.
Wigan took advantage of the makeshift defensive line as Zak Hardaker recieved the ball out the back and with McCarthy-Scarsbrook cutting inside, the full-back raced through the gap.
He failed to convert his own try with the score staying 4-6.
Warriors winger, Tom Davies then suffered a horror injury, as his foot was caught underneath his body in a tackle.
A long break in play followed with Davies being stretchered from the field.
After the long pause, Saints took control of the game.
Jonny Lomax broke on the outside of Chris Hankinson, and with just Hardaker to beat, released Regan Grace, who slid over in the corner for a six-point lead.
Just before the half-hour mark, Wigan were penalised for interference at the ruck.
This gave Coote the chance to make the score 4-12 and duly delivered.
Grace then grabbed his second try of the afternoon, following a combined 50 metre break from Luke Thompson and Lachlan Coote, who was tackled just short of the line.
A quick play-the-ball from Coote, gave Peyroux the chance to pop the ball up to Grace in the corner.
Wigan were nowhere near down and out though.
Oliver Gildart outpaced the Saints defence on the left hand edge and passed the ball back inside to George Williams, who raced underneath the sticks.
Hardaker converted to make it 10-18 at the break.
HALF-TIME: WIGAN WARRIORS 10-18 ST HELENS
It took Saints just 6 minutes to extend their lead.
This time, Danny Richardson’s skip and jump gave him the room to release Tommy Makinson on the right wing and Makinson raced away to score.
With just under an hour played, Wigan were creeping further into Saints territory but handling errors were letting them down.
The Saints made their rivals pay, and with some slick passing down the left hand edge, Regan Grace escaped tackles from Morgan Knowles and co to run away and score his hat-trick try.
Coote converted once more to make the score 10-28.
A loose pass from Sean O’Loughlin was picked off by Danny Richardson which put Saints back on the front foot.
This momentum allowed the Saints to extend their lead further as the Warriors were caught offside on the fifth tackle.
Coote converted once more to lead by 20.
Coote then grabbed another six points of his own. He picked the pocket of Hardaker in the air following a high kick from Jonny Lomax and finished off under the posts.
The game would not end without controversy though as Dominique Peyroux charged at Jake Shorrocks with his shoulder in the final 90 seconds.
The Warriors fan which remained believed the second-rower should have been sent to the sin-bin with Williams being stretchered off the field.
James Child agreed and Peyroux would leave the field for the final minute and a half.
With Wigan camped on the St Helens try line, they attempted to pick up a consolation.
However, Peyroux, Thompson and co were too strong and held on.
