What makes Costanuci interesting is how selective its success has been. On normal ground conditions, the horse has won 2 races from 9 attempts—a respectable 22% win rate—which suggests it has genuine ability on the right surface. By contrast, on other ground, the record deteriorates sharply. Trainer John Queally has had limited luck this season overall, with just one winner sent out by the yard, so Costanuci's struggles have been shared rather than unique. The horse's regular rider, Brian Hayes, has not managed a win in seven races together, which hints at a partnership that has not quite clicked or at horses that have simply run below their best when paired together. Recent form reads 2-5-8–5-4 (most recent first), a sequence showing some consistency in minor placings but no breakthrough performances.
At nine years old and with nearly three years since the last victory, Costanuci is a horse running on memory and the hope that the right race, the right surface, and the right circumstances might finally come together again. For now, it remains a solid minor race contender with a taste for normal ground—useful information for anyone watching its next outing.
