Introduction
The Panthers meet the Knights at Accor Stadium with Penrith carrying favouritism into this finals clash. The market line is 10.5 points, which asks the Panthers to win comfortably rather than simply advance. That looks reasonably close to the right neighbourhood, although Penrith's recent defensive work gives the handicap room to move a little further in their favour.
Recent scoring margins provide a useful starting point and point towards a fair line around Panthers minus 12.5, although past scores alone cannot account for current form, this week's squads or how these sides match up. The teams have faced broadly similar recent schedules, so neither receives a meaningful boost from opposition quality. Penrith also had the bye last round, while Newcastle played in Finals Week 2.
Margin

Margin combines scoring and defence into one number and anchors the recent form story.

Analysis
Penrith's ability to control possession should make Newcastle work hard for their opportunities. The Panthers have completed at 82.2% in their last five games, comfortably above the league average of 78.45%, while Newcastle have managed 77%, slightly below that mark. Penrith have also averaged 1743.8 run metres across their last five, above the league average of 1670.4 metres. That combination gives the favourites a strong platform to build pressure and makes a double digit margin easier to envisage.
Completion rate
Penrith have been considerably more reliable at completing their sets, which should help them control territory and sustain pressure.
Defence creates the sharper separation. Penrith have averaged 33.2 missed tackles in their last five games, better than the league average of 35.1, while Newcastle have averaged 40.2. The Knights have still produced 7.4 line breaks per game compared with Penrith's 5, so their attack carries genuine danger. The problem is sustaining that threat while containing a Panthers side whose opponents have averaged only 11.6 points across the same five match window. Newcastle's opponents have scored 27.2 points per game across their last five, leaving a much larger defensive question around the underdogs.
Key Players
Nathan Cleary gives Penrith another way to stretch the margin through his own running game. He has averaged 95.2 run metres across his last five games and that output has lifted to 106.7 metres across his last three. Against a Newcastle defence already missing 40.2 tackles per game, his willingness to carry the ball can create additional stress rather than allowing the Knights to concentrate solely on Penrith's outside runners.
Nathan Cleary — Run metres
Cleary's running output has lifted recently and adds another threat for Newcastle to contain around the middle of the field. The league average is based on players in the same position and is calculated using recent performance data across the competition.
Kalyn Ponga is central to Newcastle's chances of keeping this close. He has averaged 1.6 line breaks across his last five games, giving the Knights an individual threat capable of turning limited opportunities into attacking breakthroughs. Newcastle need that influence because Penrith have conceded only 11.6 points per game across their last five, and a quiet night from Ponga would make overcoming a 10.5 point start considerably harder.
Kalyn Ponga — Line breaks
Ponga's line breaking ability gives Newcastle an avenue to create the attacking moments needed to stay within the handicap. The league average is based on players in the same position and is calculated using recent performance data across the competition.
Prediction And Value Bet
Newcastle have enough attacking punch to make Penrith defend, particularly given their 7.4 line breaks per game, but the Panthers look better equipped to control how much football each side gets. Their stronger completion, superior recent defensive numbers and ability to generate 1743.8 run metres per game create the conditions for pressure to accumulate as the contest develops.
We expect the Panthers to win by around 13 points, making Panthers minus 12.5 our estimated fair line. Against a market line of 10.5, the handicap looks slightly too low rather than broadly fair. The gap is not enormous, but Penrith's defensive control and cleaner possession give them enough scope to clear the current number. Panthers to cover.
