He has one more than Not a Single Doubt, three more than Exceed and Excel and Hinchinbrook and four more than high profile sires Choisir, I Am Invincible, Snitzel, Pierro and Fastnet Rock.
It's heady stuff for a sire that stands at $11,000 and does draw parallels with I Am Invincible, who also starts his career at the same fee and has achieved resounding success.
Like I Am Invincible, Spirit of Boom gave notice of things to come at the sales of 2017 when his progeny sold above expectation.
Spirit of Boom had six yearlings average $120,00 in Book One at Magic Millions in 2017 putting him third on the most profitable sires list below.
The most expensive of those yearlings at $210,000 was Outback Barbie, who became his second stakes-winner last Saturday when taking out the BRC Calaway Gal Stakes, just minutes after his son Ef Troop won the BRC Phelan Ready Stakes.
As we come to the end of 2017, Spirit of Boom is the first season sire that has jumped out of the gates and he has a dozen entries for Magic Millions, click here to see them.
