Newcastle Diamonds will travel to Cumbria in the hope of reaching the Knockout Cup final in confident mood.
The Diamonds beat Warrington Comets by 18 points in their first leg tie at Brough Park.
Captain Mark Lemon claimed nine of his side's 54 points and has warned his teammates to not take the Comets lightly, despite going into the second leg with an 18-point lead.
Lemon said: "The job is only half done, everything is still to play for and going to Derwent Park is never an easy fixture.
"While everyone is pleased with tonight’s result- this performance will mean nothing if we do not make it to the final."
