Ireland vs South Africa
What the model says about this fixture, at either ground and at a neutral one, with the record behind it. Ratings as at 2026-08-23.
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 Ireland wins; the faded bars at each end hold everything beyond 75 points.
Margin percentiles
Eight runs in ten finished between 22 South Africa and 16 Ireland, with the middle run at level.
Those are gaps rather than scorelines. How much scoring the match produces is drawn separately — between 30 and 70 points in eight runs out of ten — so one bar covers many scores. The middle run above is 19-19 on a tight afternoon and 30-30 on an open one.
Why Ireland are not favoured
