A JWorm Racing tool

Which sires' babies win at your distance?

The Pedigree Finder is a matchmaking tool for Thoroughbred handicapping and breeding. Enter a target race distance and it instantly ranks 184 sires and 98 dam sires by how their progeny actually perform at that trip — so you can spot the pedigrees built for the race in front of you.

Dial in the trip you're targeting and choose how tightly matches must fit it. Every sire and dam sire is flagged as an Ideal fit, a Good fit, or out of range — a six-furlong sprint and a mile-and-a-quarter route call for very different families.

What it measures

Four numbers that describe a sire's babies

Every sire and dam sire in the database is profiled by the same four performance metrics, drawn from their progeny's actual race records.

AWD

Average winning distance

The distance at which a sire's offspring actually win their races — the anchor for every distance match.

Win %

Overall win percentage

How often the progeny find the winner's circle, across all starts.

FTS %

First-time-starter win percentage

How often the babies fire first time out — a critical edge for debut and maiden races.

ROI

Return on investment

What a flat bet on the progeny actually returns — the difference between horses that win and horses that pay.

How you use it

Distance in, ranked shortlist out

01

Distance matching

Slide to any distance from 5 to 12 furlongs and see which sires' progeny thrive there, each flagged Ideal, Good, or out of range.

02

Dual rankings

Sires and broodmare sires side by side — essential for judging both halves of a runner's pedigree or a planned mating.

03

First-time-starter mode

Toggle to FTS and find the sires whose babies win fresh off the debut — the edge nobody at the window has.

04

Flexible sorting

Rank by win percentage, ROI, or how precisely a sire fits your target distance. Your priorities, your order.

05

Instant search

Look up any sire or dam sire by name and pull their full four-metric profile in seconds.

06

The full database

184 sires and 98 dam sires profiled — the stallions whose names you'll actually see in the program.

Set to a mile: 85 sires and 82 dam sires match, ranked by win percentage.
Who it's for

Three ways players use it

At the windows

Handicapping a maiden race

No form to read? The pedigree is the form. FTS mode tells you whose babies win at first asking — before the crowd figures it out.

At the sale

Evaluating a yearling

Both halves of the page, profiled by real race results. See whether the sire and dam sire actually produce winners at the distances you care about.

In the shed

Planning a mating

Match a mare's family to stallions whose progeny prove out at the target trip — a ranked shortlist instead of a hunch.
