Sean McDermott
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%".
Rode around 100 times a season, almost all over hurdles and fences, winning on 4% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.02). When claiming the record reads 6% (98 rides).
The record is strongest at Wexford (9.3%, n=43) and Downpatrick (8.3%, n=48) — all clear of the rider's 4.2% baseline. It is weakest at Punchestown (1.1% over 89 rides) — the widest gap in the record. Horses returning fresh after 61+ days are the standout value angle: 5.6% strikes only just above baseline, but Fair A/E 1.67 and +6.00 to a £1 stake over 306 rides — a record the market has persistently underpriced. The market has consistently overbet first rides on a horse: 2.5% strike, Fair A/E 0.85 and −429.00 to a £1 stake over 693 rides — those runners underperformed what the price implied. J F O'Shea supplied 16% of the rides and beats the rider's average (9.7% vs 4.2%, A/E 1.37) — the partnership beats the margin-free market read. The rider also read well off a 61-180-day break (8%, n=174) and on Good to Firm going (8.2%, n=134). 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the ISF EBF Lombardstown Mares Novice Chase at Cork (Dec 2006, £26,040). The standout partner of the record was Gudnis Gracious Me (IRE) — 6 wins from 37 rides together. Seasonally, the rider fired Feb–Mar.
Riding patterns
the angles behind the record · vs 4.2% baselineEach tile is the record in that situation vs the 4.2% 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.

Quick answers
- What is Sean McDermott's strike rate?
- Sean McDermott has won 55 of 1,324 rides since 2008, a strike rate of 4.2% (as at 6 November 2026). Figures are computed from our own results archive.
- Which course does Sean McDermott do best at?
- Downpatrick by strike rate: 4 wins from 48 rides (8.3%) since 2008. 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 Sean McDermott ride most for?
- J F O'Shea, with 217 rides since 2008 — 16% of the total. That pairing has won 21 (9.7%).
- What is Sean McDermott's Fair A/E?
- 1.02, from 1,324 rides with a computed fair probability since 2008. 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.
