The broader four-year picture is modest but not empty. The standout chapter has been a long-running partnership with Avec Espoir, a horse that has given the yard its best moments — 4 wins from 27 races together. That's not a flashy number, but winning 4 from 27 attempts with one horse tells you there's a working relationship there, a horse that knows the yard and a trainer who knows the horse. Those wins matter.
What's harder to ignore is the direction of travel. Last year, O'Brien was winning roughly 1 in every 17 races — a modest rate, but a rate. This season that number has fallen to zero from 30 attempts, which is the kind of run that demands answers. Thirty runners is a reasonable sample. At some point a blank season stops being bad luck and starts being a question about whether the horses are good enough, whether the targets are right, or whether something needs to change. O'Brien is at that crossroads now.
Five years in, the CV is thin on results but not yet written off. The Avec Espoir partnership proves O'Brien can get a horse to win races. The challenge now is proving it wasn't the exception.
