Leigh Leopards 24–18 Castleford Tigers in Super League Round 18 at Leigh Sports Village Stadium. Here's how the result stacked up against the model's call, with the win-probability story and where the value landed.

Castleford Tigers' discipline couldn't tip the scales. Leigh Leopards edged them 24-18 at Leigh Sports Village Stadium, despite conceding 11 penalties to Castleford's 8. The Tigers failed to make the most of their advantage, as Leigh's backs and a cleaner game carried them through.

Lachlan Lam got Leigh off to a flying start, scoring the first try just three minutes in. Adam Cook's conversions kept the Leopards ahead, extending the lead to 12-0 after David Armstrong's try. Castleford clawed back, though. Sam Hall and Mikaele Ravalawa scored tries, both converted, levelling the score at 12-12 by half-time.

Leigh's backs, rated 981 against Castleford's 778, proved decisive after the break. Umyla Hanley scored a crucial try three minutes into the second half. Cook's consistent kicking put them back in front at 18-12. Armstrong's second try at the 53-minute mark gave them some breathing room.

Castleford had their opportunities, with 38 tackle busts to Leigh's 17. Phoenix Laulu-Togaga'e's late try brought them within six points, but time wasn't on their side. They needed more incisive running to turn those busts into points, but fell short when it counted.

Despite the loss, Castleford actually ran more metres, 1,085 to Leigh's 997. However, Leigh's fewer errors, just 11 compared to Castleford's 13, proved crucial. Castleford's backs couldn't overcome those mistakes.

Alphr's model had predicted a Leigh win with a 79% probability and a margin of 9.6 points. The actual margin was six. The predicted total score of 45 was close to the actual 42.

Castleford covered the 23.5-point start, showing competitive spirit, but it was discipline and possession that decided the game. Despite Castleford's stronger forward rating of 731 over Leigh's 726, their backs struggled against Leigh's sharp edge.

In the end, discipline and execution were key, even though the Tigers were technically more disciplined. Runs, scores, busts, the game had them all, but those three extra penalties told a significant part of the story. Ends like these linger. Back tomorrow.
