His overall career record across 11 races reads 2 wins and 3 places, meaning he has come away with something to show for himself in nearly half his outings. That overall win rate of roughly 1 in every 5 or 6 races is solid without being spectacular — but the Dundalk numbers sit well above that average, which is exactly the kind of stat that makes a horse interesting to follow. His first win there came in February 2025, and he added a second just this week on 1 April 2026, suggesting he has not only rediscovered form but timed it well heading into the spring.
The recent run of form — finishing first, then third, then drifting back to sixth, fifth, and ninth — tells the story of a horse who can be frustratingly inconsistent away from his favourite conditions. He clearly goes well on normal ground, winning 2 of his 5 races in those conditions, but when things do not suit him, he can disappear from contention entirely. That kind of horse rewards patience and specificity: you do not follow him everywhere, you watch for Dundalk on a decent surface.
A.J. Martin's yard at Summerhill has sent out 14 winners already this season, so this is not a backwater operation scraping results together — it is a functioning yard in form, and Sir Callisto's win this week adds to that momentum. He is not a superstar, and nothing about his record suggests he is about to gatecrash a big occasion. But as a horse who knows exactly where he belongs and keeps delivering there, he has earned his reputation the honest way.
