The partnership with jockey Marco Ghiani is one of the most compelling stories here. Across nine races together, Ghiani has steered Expert Agent to four wins — that's nearly 1 in every 2 rides, a 44% win rate that is extraordinary by any standard. For context, a good jockey-horse combination might click 25% of the time. Nearly half is the kind of number that makes trainers very reluctant to change things up.
Stuart Williams, based at Newmarket — the historic heartland of British flat racing — has had a strong season, sending out 67 winners. Expert Agent is one of the yard's dependable performers. The horse's last win came at Newmarket itself just five weeks ago, on 16 May 2026, and its first career win was at Kempton Park back in January 2023, so there's been a steady, consistent thread running through its career rather than a single lucky streak.
One detail stands out for anyone thinking about where Expert Agent runs best. At Lingfield Park, it has won 2 from 3 races — that's 67%, meaning it wins there more often than not. That's the hallmark of a genuine course specialist: something about the track's unique layout suits this horse in a way that defies easy explanation but shows up unmistakably in the results.
Ground conditions matter too. On normal conditions, Expert Agent has won 3 from 8 races, a 38% win rate — significantly better than its overall average. Most of its career has been spent at Class 4 level, which is mid-tier British racing, winning 3 from 21 there (14%). The fact it keeps competing and keeps finding a way to win in that company, while peaking sharply when conditions align, makes Expert Agent exactly the kind of horse a knowledgeable fan circles on the racecard: consistent, well-placed, and right now — form suggesting it's near its very best.
