Coolmore broke the record for a price paid at auction this year when parting with 3.4million guineas for a Galileo colt at the prestigious Tattersalls Book One sale.
The yearling is out of the mare Shastye, who has already produced Secret Gesture, Sir Isaac Newton and recent Beresford Stakes winner Japan.
Magnier faced stiff competition from Japanese trainer Mitsu Nakauchida but eventually his persistence paid off to give Newsells Park Stud another big success.
MV Magnier told Tattersalls: “His two-year-old brother Japan is a very nice colt, whom we think a lot of, while Andreas Jacobs’ Newsells Park is a fabulous breeding operation.”
Julian Dollar of Newsells Park Stud said: “She is a wonderful mare and the pedigree says it all, but timing is everything and Japan’s Beresford win two weeks ago just revitalised everything and brought back some interest and vibrancy to the pedigree.
“This is a lovely colt, and has always been a lovely horse, though maybe not as pretty as Sir Isaac Newton, he is strong and athletic.

“I think that Aidan (O’Brien) believes he did not get it quite right with Sir Isaac, so Coolmore was happy to come back again – I also know that Ballydoyle holds Japan in high regard.”
Shastye is back in foal to Galileo already.
