The last foal of the season at SCHLOSSGUT ITLINGEN was born just before 6:00am and it is the biggest and heaviest foal ever been born there when RUSOOKH is a sister to Gr.1 placed MOTAMARRIS and the dams of Gr.1 Irish Derby winner SANTIAGO, the Gr.1 placed LA JACONDE and the Gr.3 winners GLOUNTHAUNE and TANTHEEM. As a three parts sister to Gr. 1 winner TAMAYUZ, RUSOOKH stems from one of the best families in the stud book, as it is the family of Champions GALILEO and SEA THE STARS, as well as TORQUATOR TASSO
