Breeding and Bloodstock

Espiona, a Group 1-winning daughter of Extreme Choice, has parlayed a $3.3 million prize money return on the racetrack into a $4.15 million sale ring windfall for Denise Martin’s Star Thoroughbreds.

I Am Invincible has claimed his third straight Australian Sires Premiership, after a season where he set a new record with over $32 million in progeny earnings.

Zoustar’s shot at eclipsing I Am Invincible’s record number of Australian winners in a season is set to go down to the wire as the Widden Stud star moved to 208 for 2023/24, level with the mark I Am Invincible set in 2020/21

Although the number of active thoroughbred stallions in Australia may be on a significant decline, the 2023/24 season has seen a historically high number secure stakes success with their progeny.

Young sire sensation The Autumn Sun, who has produced three Group 1 winners from his first crop, will miss the 2024 breeding season through injury.

Godolphin has opted to retire its multiple Group 1-winning mare In Secret to a breeding career after she suffered a suspensory ligament injury.

With just over a week left of the racing season and premierships set to be crowned, it seems a good time for Run The Numbers to see which trainers, jockeys and sires have made the biggest improvement when it comes to racetrack wins this season.
