What is Ross O'Sullivan's strike rate?

Ross O'Sullivan has won 136 of 1,638 runners since 2022, a strike rate of 8.3% (as at 20 October 2026). Figures are computed from our own results archive.

Which course does Ross O'Sullivan do best at?

Killarney by strike rate: 9 wins from 55 runners (16.4%) since 2022. Read from the 15 courses with the most runners 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.

Who rides most for Ross O'Sullivan?

Tom Harney, with 159 runners since 2022 — 10% of the total. That pairing has won 17 (10.7%).

Is Ross O'Sullivan in form?

In the last 14 days: 19 runners, 1 winner, a strike rate of 5.3%. That is below the baseline of 8.3% since 2022.

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

0.93, from 1,638 runners 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 Yard Profile

Sends out around 330 runners a season, across both codes, winning with 8% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.93). Horses in first-time headgear strike at 10% (61 runs, true-first definition). The yard is quiet just now — 1 winner in the last fortnight, below its own baseline.

The read

The record is strongest at Killarney (16.4%, n=55), clear of the yard's 8.3% baseline. It is weakest at Limerick (3.1% over 64 runners) — the widest gap in the record. Debutants struggle at 2% (n=102, Fair A/E 0.61). The market has consistently overbet horses returning fresh after 61+ days: 6.1% strike, Fair A/E 0.74 and −2.42 to a £1 stake over 309 runners — those runners underperform what the price implies. Right now the yard is in a quiet spell: 1 from 19 runners in the last 14 days (5.3%, 3pts below the 8.3% baseline). Tom Harney rides 10% of the entries and edges the yard's average (10.7% vs 8.3%, A/E 1.11) — the partnership beats the margin-free market read. 8 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Friends Of The Curragh Irish Cesarewitch at Curragh (IRE) (Sep 2026, £275,000). The stable star of the record: Samrogue (IRE) — 7 wins from 40 runs for the yard. Seasonally, the yard fires May–Jul.

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. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races.

Showing the 60 most-raced of the 211 horses sent out in this window — each ran at least 10 times. Horses with fewer runs aren't listed; search finds any horse since 2005. Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Where they came from · where they went next

Of the 60 horses listed, 23 arrived from another yard in our archive, most often from Peter Fahey (2); 37 had their first archived run for this yard.

10 have since run for another yard; 50 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.
