The breakthrough came at Thirsk on 17 May 2025 — his first career win after a long wait. O'Meara noted afterwards that Mirsky had finished second in a decent race at the Ebor meeting the previous year, so the talent was always there. The key, it turned out, was getting him to race prominently, letting his natural strength do the work in the closing stages. Once that penny dropped, things moved quickly. Mirsky backed it up with a win at Epsom Downs on 6 June 2025 — a Class 2 race, which puts it among the better contests in Britain. That prompted O'Meara to float the idea of the Hunt Cup, one of the most competitive mile races of the flat season.
What makes Mirsky particularly interesting is his record at Thirsk specifically. He has won 2 of his 3 races there, which is a remarkable return at a single track — for context, his overall win rate is 3 wins from 17 races, roughly 1 in every 6. At Thirsk alone, he wins 2 in every 3. That kind of dominance at a specific course is not a coincidence — some horses simply suit a track's shape and nature, and Thirsk appears to be Mirsky's happy hunting ground.
His overall record does reflect how tough life is at Class 2 level — before his recent purple patch, he had managed just 1 win from 12 races at that grade, or roughly 1 in every 12 attempts. The fact he has now cracked it twice in quick succession, and been placed five more times across his career, suggests a horse who has always been good enough but needed everything to fall right. He raced again just yesterday, meaning he is bang in form and being kept busy — which is exactly what O'Meara's yard does: they have sent out 107 winners already this season, making them one of the most productive operations in the north of England right now.
