Carroll trains out of Cropthorne in Worcestershire, and his operation is clearly in fine form — 136 winners sent out this season alone is a serious number, the kind that puts a yard firmly in the conversation among the busiest and most productive in the country. Masqool is one of the yard's steadier contributors, doing most of its work at Class 6 level, the entry point of British racing. At that tier, the horse has won 8 from 34 races — nearly 1 in every 4 — which suggests it competes at exactly the right level for its ability, and more often than not makes a race of it.
The partnership with jockey Dougie Costello is worth noting. In 32 races together, Costello has guided Masqool to 6 wins — a win rate of 19%, or roughly 1 in every 5 rides. That is meaningfully better than the horse's overall average, which tells you something real: this is a jockey who understands the horse, and when the two are reunited, it is worth paying attention.
Masqool also has a favourite address. At Lingfield Park, the horse has won 4 times from 16 races — 1 in every 4 — which makes it a genuine course specialist. Lingfield has a unique all-weather track with a tight, downhill bend that not every horse takes to naturally, so finding one that clearly enjoys the place is useful knowledge.
The last win came at Chelmsford on 30 August 2025, nine months ago now, and the most recent six races have brought a mixed bag — two placings among some quieter efforts. Raced just yesterday and still active, Masqool is clearly being kept busy. Whether another win is around the corner is hard to say, but a horse that has won 12 times and still turns up every few weeks at the age of eight deserves a certain kind of respect.
