The most compelling thread in Young's training career so far is his partnership with Darkest Day, a horse that has raced 30 times under his care and won three of them. That's a 10% win rate from that one horse alone — comfortably better than the yard's overall average — which suggests Young knows this horse well and has worked out how to get the best from it. In a small yard, having one horse you genuinely understand can make a real difference.
Normal conditions appear to suit his runners best. On standard ground, the yard has won 1 from 17 races, a 6% win rate — twice the seasonal average. That's a small sample, but it's a consistent signal worth noting. When the ground is normal and the conditions are straightforward, Young's horses seem to perform closer to their potential.
Four years in, William Young Jnr is still building. The numbers are modest, but the direction of travel is the right one.
