What is Michael O'Sullivan's strike rate?

Michael O'Sullivan has won 96 of 1,187 rides since 2008, a strike rate of 8.1% (as at 13 November 2026). Figures are computed from our own results archive.

Which course does Michael O'Sullivan do best at?

Fairyhouse by strike rate: 12 wins from 99 rides (12.1%) 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 Michael O'Sullivan ride most for?

Barry Connell, with 158 rides since 2008 — 13% of the total. That pairing has won 24 (15.2%).

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

0.92, from 1,187 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.

KTB Rider Profile

Rides around 60 times a season, almost all over hurdles and fences, winning on 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.92). Riding last-time-out winners the record reads 15% (117 rides).

The read

The record is strongest at Ballinrobe (15.2%, n=33) and Fairyhouse (12.1%, n=99) — all clear of the rider's 8.1% baseline. Rides on last-time-out winners have been a positive signal at 14.5% (n=117, Fair A/E 1.05). Barry Connell supplies 13% of the rides and beats the rider's average (15.2% vs 8.1%, A/E 1.02) — the market has that partnership priced right. The record reads poorly in Flat races — 1.8% over 57 rides, 6.3pts 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 8.1% 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.
