The trainer is J P Flavin, operating out of Tramore in Co Waterford. It's a small yard by the standards of the big Irish operations, but they've sent out 10 winners already this season, which tells you this is a stable in decent form and worth paying attention to. A winner from a yard like this tends to be well-prepared — small trainers don't waste entries.
Beyond that, there simply isn't a form book to consult. Ellis Brittle is a blank page. Whether the talent suggested by the breeding shows up on a racecourse is the whole question, and the first run will answer it.
