The real meat in Merrijig's record lies in the partnership with jockey Gina Mangan. When they team up, something clicks—Mangan has ridden the horse to 3 wins from just 12 races together, a 25% win rate that is substantially better than Merrijig's overall record. That kind of lift suggests Mangan understands how to get the best out of this horse, which is the sort of detail that matters when studying form. Trained by John Berry at Newmarket, Merrijig is part of a yard that has sent out 13 winners this season—a modest tally that reflects the competitive level at which Berry operates.
The horse has not won in 10 months, with the last success coming at Newcastle back in November 2025. Recent form has been patchy: across the last six outings it has finished 4th, 6th, 3rd, 2nd, 3rd, and 6th. These are not the numbers that suggest an imminent return to the winner's circle, yet the horse raced just a day ago, which shows it is still active and still being given opportunities. Merrijig races most often at the lower levels of the sport, posting a 2-win record from 15 Class 5 races. On normal ground, though, it has been notably stronger—2 wins from just 3 races on standard conditions suggests that firmer or softer going does not suit as well. If another victory comes, it will likely be when those conditions align and Mangan is in the saddle.
