Kementari could return to the races in 2020 after early indications his stallion career is to be short-lived due to fertility problems.
The 2018 Randwick Guineas winner is a much-heralded freshman sire for Godolphin at the Kelvinside property in NSW, but after less than four weeks of serving mares, analysis suggests he could be sub-fertile, which means he will be categorised as an unsatisfactory breeder.
The news comes as a major blow for Godolphin as Kementari was seen as a potential new star of the breeding barn.
The five-year-old son of Lonhro began stallion duties this season at a fee of $33,000 and had bookings of well over 150 mares but the owners have since been informed of his fertility problems.
It is understood that Godolphin will not make a decision on whether Kementari resumes his racing career until after the breeding season.
Across a 19-start career Kementari was unlucky not to add to his Group 1 tally of wins, with narrow placings in a Caulfield Guineas, Memsie Stakes and Orr Stakes.
His sire Lonhro remains as one of Godolphin’s champion stallions. The sire of 71 Stakes winners of 144 Stakes races attracts a fee of $77,000 in this, his 16th season.
