What is James O'Sullivan's strike rate?

James O'Sullivan has won 67 of 1,610 rides since 2008, a strike rate of 4.2% (as at 14 November 2026). Figures are computed from our own results archive.

Which course does James O'Sullivan do best at?

Kilbeggan by strike rate: 10 wins from 86 rides (11.6%) 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 James O'Sullivan ride most for?

P J Rothwell, with 769 rides since 2008 — 48% of the total. That pairing has won 26 (3.4%).

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

0.78, from 1,610 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.

The read

The record is strongest at Kilbeggan (11.6%, n=86), Ballinrobe (8.3%, n=72) and Listowel (9.1%, n=33) — all clear of the rider's 4.2% baseline. The market has consistently overbet first rides on a horse: 3% strike, Fair A/E 0.76 and −413.15 to a £1 stake over 639 rides — those runners underperform what the price implies. P J Rothwell supplies 48% of the rides and matches the rider's average almost exactly (3.4%, A/E 0.74). 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 May–Jun.

Each 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.
