Grey Horizon

The partnership with jockey Kieran O'Neill is the clearest sign of that. Together they have won five of 11 races — a 45 percent win rate that doubles the horse's overall win rate. That is not luck; that is a rider who understands how to get the best from this particular animal. Scott Dixon's Rolleston yard, which has sent out 33 winners already this season, appears to be running the horse well, and recent form suggests momentum. Grey Horizon won 3 weeks ago at Bath and has claimed two wins in its last six outings, including a victory just yesterday, which means the horse is actively racing and sharp.

Southwell is where Grey Horizon shows its strongest hand: two wins from four races at that track amounts to a 50 percent win rate, genuinely exceptional. In Class 6 races — the sort of competitive but not elite contests where this horse typically competes — it has won three of eight starts, a 38 percent win rate that sits well above its career average. The form picture is uneven: a ninth-place finish in the last six races sits alongside wins and places, suggesting the horse runs hot and cold. But with O'Neill in the saddle, a sharp trainer behind it, and a win under its belt from yesterday, Grey Horizon looks a horse worth watching in its grade.
