What is James O'Sullivan's strike rate?

James O'Sullivan has won 28 of 592 rides since 2022, a strike rate of 4.7% (as at 28 October 2026). Figures are computed from our own results archive.

Which course does James O'Sullivan do best at?

Kilbeggan by strike rate: 6 wins from 42 rides (14.3%) 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 James O'Sullivan ride most for?

P J Rothwell, with 329 rides since 2022 — 56% of the total. That pairing has won 14 (4.3%).

What is James O'Sullivan's Fair A/E?

0.82, from 592 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.

KTB Rider Profile

Rides around 120 times a season, almost all over hurdles and fences, winning on 5% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.82). The edge shows sharpest with horses returning fresh: 6% off breaks of two months or more (94 runs). Rides mostly for P J Rothwell — 56% of rides in the window.

The read

The record is strongest at Kilbeggan (14.3%, n=42) and Ballinrobe (13.3%, n=30) — all clear of the rider's 4.7% baseline. It is weakest at Punchestown (0% over 57 rides) — the largest sample in the record, and the widest gap. The market has consistently overbet rides in big fields of 14 or more: 3% strike, Fair A/E 0.71 and −254.75 to a £1 stake over 367 rides — those runners underperform what the price implies. P J Rothwell supplies 56% of the rides and matches the rider's average almost exactly (4.3%, A/E 0.81). The rider also reads well off a 61-180-day break (9.8%, n=51). One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the BoyleSports, Proud Sponsors Since 2014 Novice Handicap Chase at Fairyhouse (Mar 2024, £26,550). Seasonally, the rider fires Apr–Jun.

Each tile is the record in that situation vs the 4.7% baseline — descriptive splits with the sample always shown, not tips. 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.
