With the least runners of any of the top six sires, Not a Single Doubt has
already posted two Group I winners in Samadoubt and Scales of Justice, so it's bee
a memorably good start to spring for the son of Redoute's Choice, who stands
this spring at a fee of $110,000.The loss of Sebring has been highlighted with his rush of spring success, while it's been business as usual for I Am Invincible, whose 31 winners is the most of any sire.
The youngest sire of the group is Pierro, who might not have had a stakes-winner yet, but his avalanche of metro winners has him riding high and many of those winners offer stakes potential while his star sprinter Pierata may well be the horse to beat in The Everest following his slashing return in the Group III ATC Concorde Stakes last Saturday.
Established champion sires Fastnet Rock and Snitzel round out the group of million
dollar earning sires, which looks set for rapid expansion in coming days with So You Think,
Written Tycoon, All Too Hard and Exceed and Excel all just shy of the mark.
