What is Michael O'Sullivan's strike rate?

Michael O'Sullivan has won 84 of 1,012 rides since 2022, a strike rate of 8.3% (as at 28 October 2026). Figures are computed from our own results archive.

Which course does Michael O'Sullivan do best at?

Fairyhouse by strike rate: 11 wins from 87 rides (12.6%) 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 Michael O'Sullivan ride most for?

Barry Connell, with 156 rides since 2022 — 15% of the total. That pairing has won 24 (15.4%).

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

0.89, from 1,012 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

The read

The record is strongest at Ballinrobe (16.1%, n=31) and Fairyhouse (12.6%, n=87) — all clear of the rider's 8.3% baseline. It is weakest at Wexford (2.9% over 35 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 14.6% (n=103, Fair A/E 1.02). Barry Connell supplies 15% of the rides and beats the rider's average (15.4% vs 8.3%, A/E 1.03) — the market has that partnership priced right. The record reads poorly beyond 3m — 3% over 33 rides, 5.3pts below the baseline. 12 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Nathaniel Lacy & Partners Solicitors '50,000 Cheltenham Bonus For Stable Staff' Novice Hurdle at Leopardstown (Feb 2023, £88,500). The standout partner of the record: Marine Nationale (IRE) — 6 wins from 8 rides together. Seasonally, the rider fires Mar–Apr.

Each tile is the record in that situation vs the 8.3% 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.
