The first win only arrived in December 2024, at Cork, meaning this horse spent a long career learning the game before finally getting that breakthrough. Then, just over a year later, came a second victory — at Limerick on 12 March 2026, only a fortnight ago. Two wins is not a dramatic haul, but when you consider the persistence it takes to keep placing and keep competing across 25 races, there is something quietly admirable about a horse that keeps showing up in the frame.
The partnership with jockey Phillip Enright is central to whatever success One And Only has had. Enright has been in the saddle for 18 of those 25 races, and both career wins have come with him riding — that is a 100% record when it comes to the days that actually mattered. His win rate across their time together sits at 11%, or roughly 1 in every 9 rides, which is meaningfully better than the overall career average. When McKiernan wants the best out of this horse, Enright is clearly the man he calls.
The recent form makes for interesting reading: a win, a couple of unplaced runs, a third, another unplaced effort, and then a second — all within the last six races. That kind of patchy but present form suggests a horse that needs things to fall right, but when they do, it competes. With McKiernan's yard having sent out 4 winners already this season and One And Only having raced just 17 days ago, this is a horse still very much in the mix — not winding down, but seemingly hitting a form curve right now that its the yard will be keen to make the most of.
