Thunder Blue

That level is Class 4, and it's here where Thunder Blue looks most at home. Three wins from 9 races at this grade works out at 33%, or roughly 1 in every 3 — a genuinely impressive figure that shows when the conditions are right and the competition is pitched correctly, this horse can be a real factor. Compare that to its overall record and the picture becomes clear: drop it into the right race, and it delivers.

The first win came at Goodwood in June 2023, and Wigham was openly excited about what might follow, talking up potential entries at Ascot's biggest early-summer races for younger horses. The trajectory since then has been steady rather than explosive, but there has been progress. The most recent victory came at Salisbury in September 2025 — eight months ago now — and the last six runs tell a mixed story: a win, a close second, and then a run of results that suggest the horse has found things tougher lately, finishing as far back as 18th in one outing.

Saffie Osborne has partnered Thunder Blue more than anyone else, riding in 10 of its 27 races for 1 win together — a 10% win rate from that partnership. The pair haven't yet clicked into the kind of regular success that makes a jockey-horse combination memorable, but Osborne knows this horse better than most.

Wigham's yard has sent out 12 winners already this season, so the operation is in decent form. Thunder Blue raced just yesterday, which means fitness isn't in question. Whether it can rediscover the spark of that Salisbury win is the interesting question — but at its best, in the right race at the right level, this is a horse that wins roughly one in three. That's not a horse to dismiss lightly.
