The Aga Khan Studs will send four three-year-olds from the yards of Michael Halford and John Oxx for the forthcoming Tattersalls Horses In Training sale at Newmarket on 10th to 12th July.

Out of a full sister to champion racehorse and successful sire Sinndar, Sinour was beaten a head into second place on his seasonal debut. The colt by Observatory recently finished fifth at Tipperary.

From the family of Zarkava, Zarkiyr (Acclamation) placed second by a short head in a handicap at the Curragh on 9th June. Previously, he had finished fifth in his last two maiden races. The colt is a half-brother to Deauville winner Zardaba and to Zarkal, placed on the flat and over jumps in France. His second dam Zarkiya won the Gr.3 Prix de Sandringham and is a half-sister to prolific jumps performer Zarkali and to Zarkasha, dam of Zarkava.
