Plymouth Devils defeated third-placed Ipswich 48-42 to get their sixth straight Premier League home win.
Reserves Gino Franchetti and James Cockle delivered season-best returns to help an injury-hit Plymouth to two valuable league points.
Franchetti top-scored with 12+1 and Cockle finished with 10+2.
Team Manager Gary Spiller said: "I'm thoroughly delighted, confidence is high and there's a great spirit in the camp right now."
The win came at a cost though, after Danish star Jesper Kristiansen crashed out in heat five and was subsequently ruled out of the rest of the meeting.
"We lost a big heat-leader tonight through injury just as we did last week, but we've still managed to win both matches," Spiller added.
"If tonight's and last week's situation had occurred earlier in the season we'd have lost, but I've installed belief into the boys and that's helping to produce these results."
The win leaves Plymouth four points adrift at the bottom of the Premier League table but they have six matches in hand on nearest rivals Leicester.
The Devils' away match at Workington on Saturday was postponed due to rain.
