Royal Ascot Day Two: What Smartform’s Breeding Data Says, Race by Race

As yesterday: these aren’t tips. They’re what the Smartform breeding data makes of Wednesday’s runners, and we’re looking for value in the prices from a breeding perspective. The judgement on how to use that data, and any bet, stay yours.

The method is the same throughout. It all comes out of Smartform’s breeding tables — daily_dams_insights and daily_sires_insights, which score every runner’s dam and sire line by distance and going — together with an experimental nicks layer we’ve been building that looks at the cross of sire and damsire. Across thousands of past races we have worked out where breeding genuinely points to a winner and where it tells you nothing, and what follows is that work turned on the second day’s card.

One number to keep in mind throughout: PRB, percentage of rivals beaten, is our field-size-adjusted measure of how well a sire’s or dam’s runners have run on average. 0.50 is dead average; the further above, the better the typical run. It is steadier than strike-rate, which jumps around on small samples — and small samples are the thing to watch all week.

2:30 — Queen Mary Stakes (Fillies’ Group 2, 5f, 2yo)

A juvenile sprint, so — as in yesterday’s Coventry — it is almost entirely the sire’s story, and one sire towers over the rest: Wootton Bassett, with very nearly a winner in four of his runners over the trip on much the biggest sample in the field. His filly here is Victorious, and she is also the odds-on favourite. So once again the breeding backs the market rather than overturning it. Sioux Nation, sire of the second favourite Alta Regina and two others, heads the next tier.

Leading, well-sampled profiles shown. One-run sires (such as Celtic Dispute’s, which posts a flattering 0.905 off a single runner) are left out as noise. Forecast prices in decimal.

Reading the columns. Runs is how many of that sire’s runners we have in five- to seven-furlong two-year-old races over the past five years — the weight of evidence behind the figure; Win % is how often they won; PRB as above.

The figures agree with the market — and point, in passing, to the juvenile sprint sire of the meeting.

3:05 — Queen’s Vase (Group 2, 1m6f, 3yo)

The most interesting race on the card for us, and the one where our work has the firmest ground under it. The Queen’s Vase is a top-class staying race run at level weights — no handicapper to claw the best horse back — by three-year-olds being asked to stay a mile and six for the first time. Their own form, gathered over shorter trips, cannot tell you whether they get the distance. The breeding can, and across several hundred staying races we have shown the “nick” — the cross of sire and damsire — to be a genuine guide to which of them will.

This year it could hardly be clearer. Wareeth, by Sea The Stars out of a Motivator mare — two of the stoutest influences going — is the only runner whose cross has a real staying record, and it is a striking one: five wins from seven at the trip. At around 11/1 he is not the market’s pick. The two at the head of the betting, Galiyan and Limestone, have crosses with no staying record to read at all — their stamina is unproven on the page as much as on the track.

Only crosses with at least four runs at 1m6f or beyond in the last five years can be read; every other runner’s cross is untried over the trip. Forecast prices in decimal.

Reading the columns. Runs and Wins are that exact sire-and-damsire cross’s record in staying races (1m6f and beyond) over the last five years. A dash means the cross has fewer than four staying runs — too little to read, which in this race is most of the field.

The nick points firmly to Wareeth, and to a stamina question mark over the favourites. A confident lean rather than a lock — it rests on seven runs — but this is exactly the race the signal is built for.

3:40 — Duke Of Cambridge Stakes (Fillies’ & Mares’ Group 2, 1m)

The fillies’ answer to yesterday’s Queen Anne, and the same verdict: exposed older milers in a sharp market, with nothing in the pedigrees the betting has not already counted. One to leave alone.

4:20 — Prince Of Wales’s Stakes (Group 1, 1m2f)

One of the few races where the dam’s side has historically not just named the winner but offered a price for it. At a mile and a quarter, a mare’s record as a producer carries real weight, and here it does proper work. It backs last year’s winner, Ombudsman (his dam four wins from seven at the trip), to the hilt — but, tellingly, it has nothing to say for the bare favourite Daryz, whose dam has barely a runner to her name at this level. And at longer prices it likes Minnie Hauk and Almaqam, both out of mares with strong middle-distance records.

The dam’s own runners in mile-and-a-quarter-ish races (1m1f–1m4f) over the last five years. Dam samples are smaller than sire samples by nature, so weigh the runs column accordingly. Forecast prices in decimal.

The dam confirms Ombudsman and queries Daryz — and, for those wanting a price, flags Minnie Hauk and Almaqam.

5:00 — Royal Hunt Cup (Heritage Handicap, 1m, ~30 runners)

Our textbook case of breeding sorting a field without being able to win it. In a thirty-runner mile handicap the figures will rank the runners perfectly respectably, but the weights and the sheer size of the field wash any edge clean away by the line — we have measured it doing exactly that, year after year. Sorts, but does not pay. Leave alone.

5:35 — Kensington Palace Stakes (Fillies’ & Mares’ Handicap, 1m)

The same race in all but name — a big-field mile handicap, this time for fillies and mares. The same verdict follows. Leave alone.

6:10 — Windsor Castle Stakes (Listed, 6f, 2yo)

Back to the juvenile sprinters, and back to the sire — though this is a race that has flattered to deceive on small samples before, so we read it with one eyebrow raised. The good news is the leading profiles here are deep ones. Wootton Bassett tops the list again, which makes him the sire of the favourite in both of the day’s two-year-old sprints — the juvenile sire of the meeting, plainly. His colt Sergei Diaghilev is the favourite. The one the breeding rates well above its price is Alfred Wallace, by Dubawi — a 23.6% strike-rate profile on 300-plus runs, available at around 20/1.

Leading profiles; deep samples preferred. Bayside Boy’s eye-catching 31.3% rests on only sixteen runs, so treat it with caution; one-run sires are left out. Forecast prices in decimal.

The favourite has the best engine again; Alfred Wallace is the one the breeding fancies more than the market does.

So that is Day Two. Two of the day’s three short-priced two-year-old favourites are by the same sire, Wootton Bassett, and the breeding simply nods along with the market in both; the older milers and the big mile handicaps are races to leave well alone. The day belongs to the Queen’s Vase — a Class 1 staying race at level weights is precisely where our work has its firmest footing, and this year it has handed us a clear one in Wareeth.

All of it comes straight from the Smartform data: run the same figures yourself in daily_dams_insights and daily_sires_insights and you will see the same picture. As ever, this is analysis from a very specific lens — a lens worth following race by race, win or lose.
