The numbers that stand out most are on dry ground and at Redcar. On fast, dry ground, Diamondonthehill has won 4 of his 11 races — that is a 36% win rate, which is extraordinary at any level of the sport. For context, most racehorses win fewer than 1 in 10 races across a career. At Redcar specifically, he has won 2 of just 3 visits, making him about as reliable a course specialist as you will find. Something about that track clearly suits him.
His most frequent jockey is Paul Mulrennan, who has ridden him in 8 races and won once together — roughly 1 in 8. That is not a partnership that has clicked consistently, but the horse's quirky temperament may have as much to do with that as anything else. At Thirsk recently, he travelled beautifully, moved into contention like the best horse in the race, and then simply stopped trying — losing by a neck to Cerulean Bay in a finish he arguably should have won. His trainer is refreshingly candid about it: more ability than he cares to show.
His last win came at Lingfield Park on 28 April 2025, so it has been 14 months since he visited the winner's enclosure. He typically competes at Class 4 level — the solid middle ground of British racing — and has won 4 of his 23 races at that grade, roughly 1 in 6. He raced just yesterday and is still very much in action, with an entry at Thirsk apparently on the horizon. Given what he did there last time — almost winning despite himself — dry ground and a fast enough pace could be the combination that finally unlocks him again.
