The most important relationship in his career so far is with trainer Grant Tuer, and the statistics tell a clear story. Stammers has ridden 175 races for Tuer's yard, winning 16 of them — the same rate of roughly 1 in every 11 as his overall record. That consistency across such a large number of rides suggests this is not a casual arrangement. When a jockey and trainer work together at that volume, they develop a shared language: how a horse is likely to run, when to be patient, when to press. That kind of trust takes time to earn.
Where Stammers genuinely stands out is on wet, muddy ground. In races run on heavy, waterlogged turf he has won 1 from just 3 rides — a 33% win rate, or 1 in every 3. The sample is small, so it would be wrong to call it a defining strength just yet, but no good jockey wins a third of their races in any condition by accident. It is worth watching whether that number holds as his career develops, because an edge on testing ground in the British winter is a genuinely useful thing to have.
Four years in, 100 winners banked, and a stable first-call relationship with an established trainer — Stammers is at the stage of his career where the foundations are down and the question is what gets built on top of them.
