My Calyx Cen wins Prix Sigy, boosts Royal Ascot hopes

My Calyx Cen did more than land the Group 3 Prix Sigy at Chantilly. He announced himself as a live Royal Ascot player, sweeping past a deep international field in a 13-runner, 5½-furlong test and emerging with his profile transformed.

Sent off at 8-1, the son of Calyx was ridden positively by Aurelien Lemaitre and settled into the race as the tempo lifted. Once My Calyx Cen matched strides with Argentine Tango and edged in front inside the final two furlongs, he always looked the horse most likely to keep finding. He held Kimi Rey and Afjan safely to the line, a finish that underlined both his speed and his ability to handle pressure against a select field.

The value of the Prix Sigy as a trial was clear in the names around him. British and Irish fillies were in the mix, along with some of the better three-year-old sprinters from France and Italy, so this was no routine domestic win. It was the kind of international benchmark that can redraw the early-summer sprint picture in a single afternoon, and My Calyx Cen answered it with authority.

His progression makes the result even more striking. He started his career over a mile before being dropped back in trip and sharpened into a sprinter, and that repositioning has now produced four straight wins. After a recent Listed success over 6½ furlongs, trainer Patrik Olave Valdivielso decided to test him again over a faster 5½f, and the move paid off with the trainer’s first Group-race victory in France.

That matters for the next decision as much as the result itself. Valdivielso has already seen enough to suggest bigger targets are warranted, and the Commonwealth Cup at Royal Ascot now looks a natural question for a horse whose profile is rising fast. The combination of a strong pedigree, tactical versatility and the ability to travel through different pace scenarios gives him a case far beyond the bare form figure.

The win also fits a broader pattern for Yeguada Centurion, whose recent success with horses such as Blue Rose Cen and Big Rock has built real momentum at the top end of the sport. My Calyx Cen’s Chantilly performance added another high-level strike to that record and, in doing so, made the Royal Ascot conversation feel immediate rather than speculative.
