The backbone of his career so far has been his relationship with trainer Grant Tuer. Of Stammers' 109 career winners, 20 have come from 175 rides for Tuer's yard — an 11% win rate, or just over 1 in every 9 races. That kind of long-running partnership is worth more than the numbers suggest. When a trainer keeps booking the same jockey year after year, it tells you something: there is trust, communication, and a shared understanding of how to get the best from a horse. For a young rider still finding his feet, having that stable base is invaluable.
What gives Stammers a genuine edge is his record at Musselburgh. Five winners from 18 races at that track might sound modest, but winning more than 1 in every 4 races at a specific course is the kind of stat that makes trainers take notice when they are looking for a jockey who knows the place. Musselburgh has its quirks — a tight, flat oval that rewards good positioning and a cool head — and Stammers clearly feels at home there.
He also shows a taste for the conditions that sort out the field. On very wet, muddy ground his record reads 1 winner from just 3 races — a small sample, but a 33% win rate, or 1 in 3, is striking. Some jockeys shrink when the ground gets testing; others seem to come alive. Early signs suggest Stammers belongs to the second group. At 109 winners and climbing, with his win rate improving season on season, the trajectory is clear.
