STALLION sons of the great Galileo (by Sadler’s Wells) are making an impact in both the northern and southern hemispheres and already nine of them have sired at least one winner at the highest level on the flat. With more than 230 individual stakes winners to his name, so far, it should be no surprise to anyone that Galileo has a large and growing number of younger sons in active service too, stallions who are in the early years of their new careers.
