Saffie Osborne
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%".
Rides around 540 times a season, almost all on the flat, winning on 13% of them — beating the margin-free market read across five seasons (Fair A/E 1.12). Riding last-time-out winners the record reads 17% (310 rides).
The record is strongest at Chepstow (24.2%, n=66), Newcastle (AW) (22.7%, n=66) and Brighton (20.2%, n=109) — all clear of the rider's 12.6% baseline. Rides on last-time-out winners have been a positive signal at 17.4% (n=310, Fair A/E 1.16), but in Group and Graded company the record reads poorly at 6.8% (n=118, Fair A/E 0.90). Rides in big fields of 14 or more are the standout value angle: 8.9% strikes only just below baseline, but Fair A/E 1.57 and +64.93 to a £1 stake over 381 rides — a record the market has persistently underpriced. Jamie Osborne supplies 28% of the rides and matches the rider's average almost exactly (12%, A/E 1.08) — the partnership beats the margin-free market read. 8 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Betfred St Leger Stakes at Doncaster (Sep 2026, £396,970). The standout partner of the record: Miss Sligo (IRE) — 6 wins from 35 rides together. Seasonally, the rider fires Aug–Sep.
Riding patterns
the angles behind the record · vs 12.6% baselineEach tile is the record in that situation vs the 12.6% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

KTB’s figures
the forward record · since 5 Oct 2026KTB’s figures on this rider’s mounts since 5 Oct 2026: the KTB Selection in 12 runs (won 2, 1 did not run) · top-rated on KTB Rating in 5 runs (won 2) · fastest on KTB Speed in 4 runs (won 2) · to 22 Oct 2026.
Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
Quick answers
- What is Saffie Osborne's strike rate?
- Saffie Osborne has won 340 of 2,693 rides since 2022, a strike rate of 12.6% (as at 14 November 2026). Figures are computed from our own results archive.
- Which course does Saffie Osborne do best at?
- Brighton by strike rate: 22 wins from 109 rides (20.2%) since 2022. Read from the 15 courses with the most rides on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.
- Which yard does Saffie Osborne ride most for?
- Jamie Osborne, with 747 rides since 2022 — 28% of the total. That pairing has won 90 (12%).
- What is Saffie Osborne's Fair A/E?
- 1.12, from 2,678 rides with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
