Castleford Tigers 36–34 Leeds Rhinos in Super League Round 19 at The OneBore 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 edged Leeds Rhinos 36–34 at The OneBore Stadium. Despite the close scoreline, Leeds had a clear statistical edge in run metres, racking up 1,512 to Castleford's 1,091. However, they couldn't turn this advantage into a win, hampered by errors and penalties.

Leeds started strong, leading 20–16 at half-time. James McDonnell opened the scoring early, and Alfie Edgell added to their tally. But Castleford clawed back, with Jason Qareqare scoring twice, playing a key role in their second-half surge. Their ability to convert line breaks into points was crucial.

Despite Leeds' forward strength, rated 848 to Castleford's 742, it didn't translate into a win. Castleford's backs and halves stepped up, outperforming expectations. Their hooker, rated 1059, controlled the ruck, overshadowing Leeds' 641-rated counterpart.

Errors plagued Leeds, with 10 turnovers compared to Castleford's 5. Discipline also played a part, as Leeds conceded six penalties to Castleford's four. In tight matches, these basics often decide the outcome.

Castleford's defence was relentless. They busted 38 tackles to Leeds' 33 and made eight line breaks. While Leeds had more metres, Castleford's defensive setup kept them in check.

The comeback was sealed late, with Qareqare and Jack Ashworth scoring. Tom Weaver's conversions and a penalty goal pushed the Tigers ahead. Leeds' late try by Brodie Croft wasn't enough to change the result.

Pre-match, the model favoured Leeds with a 69% chance of victory and a predicted 9.5-point margin. Castleford's win was a statistical upset, defying the 20.5-point line. The game's 70 points far exceeded the predicted 41.

Castleford Tigers showed that stats don't always determine the outcome. It's about seizing opportunities on the field. Wins and losses are decided in the moment.
