Bayonne vs Scarlets
What the model says about this fixture, at either ground and at a neutral one, with the record behind it. Ratings as at 2026-08-24.
Each figure is 5,000 simulations of this fixture. The score is where those runs are centred, not a likely scoreline — a rugby result is spread far too widely for any single one to be likely.
How the runs finished
Winning margin across 5,000 simulations of this fixture. Bars right of the centre are Bayonne wins; the faded bars at each end hold everything beyond 75 points.
Margin percentiles
Eight runs in ten finished between 13 Scarlets and 24 Bayonne, with the middle run at 4 Bayonne.
