Runner-up of the Group 3 Jaeger-Lecoultre Molecomb Stakes at Goodwood on last outing, the two-year-old Aesterius confirmed previous good runs by landing the Group 3 Prix d’Arenberg at Parislongchamp in Paris. Aesterius is owned by Wathnan Racing and trained by Archie Watson. Ridden by James Doyle, the British-trained colt was fast away from the stalls and made all. With Treasure Isle on the girth of the leader, Aesterius was quickly on top of his rivals. Kaadi was a good second while Treasure Isle came third.
