Teofilo raced only as a juvenile, and the same is true of Holy Roman Emperor (by Danehill), the Coomore Stud stallion whose daughter Mango Diva won the Group 2 Kilboy Estate Stakes over nine furlongs at the Curragh on Sunday.

Although born the same year, and although the Kildangan Stud team member beat him both times they met on the track, it is Holy Roman Emperor who has been at stud for longer, as he covered his first book at the age of three, whereas Teofilo’s career began as a four-year-old.

Holy Roman Emperor has, up to Monday night, sired 41 stakes winners, and they include the New Zealand 1000 Guineas winner Rollout The Carpet, the Hong Kong Grade 1 star Designs On Rome, the classic-placed French Group 1 scorer Morandi, and the runaway Group 1 1000 Guineas heroine Homecoming Queen.

Mango Diva holds an entry in next month’s Group 1 Markel Insurance Nassau Stakes at Goodwood, and although further improvement is required if she is to win such a contest, this dual pattern scorer has only run nine times to date, and so another step forward is possible.

She is owned and bred by the Antoniades family and she is the second foal out of the tough and talented Mango Mischief (by Desert King), which makes her inbred 2x3 to Danehill (by Danzig).

We can only guess as to whether or not that level of inbreeding has had any real effect on her capabilities as a racehorse, or how it might impact on her future career at stud, if at all, but what we can see clearly is that she is a daughter of a successful sire, and out of a triple 10-furlong stakes winner whose victories included the Group 3 Golden Daffodil Stakes at Chepstow.

The record of her parents gave her every chance of being a highly talented racehorse, and when her dam had the added claims of being a half-sister to a pair of blacktype earners, and out of a winning half-sister to a pattern-placed stakes winner, then her potential to succeed was greater than for most.

The more prolific of Mango Mischief’s two blacktype siblings is Bonecrusher (by Revoque), a stakes-placed four times scorer whose rating stayed in the 102-107 range for two full years.

Their half-sister Eurolink Raindance (by Alzao) reached as high as 109 in England, and her various pieces of blacktype included her third place finish in the Listed European Free Handicap at Newmarket and the runner-up spot in the Listed Conqueror Stakes over a mile at Goodwood.

That filly has since become a somewhat successful broodmare whose winners include Toymaker (by Starcraft), a gelding whose most recent of four victories came over eight and a half furlongs at Wolverhampton in February.

Mango Mischief is also a half-sister to the dual six-furlong scorer Eurolink Sundance (by Night Shift), and the most prolific of that mare’s offspring is the sprint handicapper Mango Music (by Distant Music), a winner of 10 of her 80 starts.

The 12-furlong Salisbury winner Eurolink Mischief (by Be My Chief) is the grandam of Mango Diva, and the mare was a half-sister both to Lord Eurolink (by Danehill), who won eight times from eight to 11 furlongs, and to Duke Of Eurolink (by Jupiter Island), who won a 12 furlong Listed handicap at Goodwood, and whose placings included third in the Group 3 St Simon Stakes at Newbury.

Mango Mischief and her Group 2-winning daughter Mango Diva are the best of the blacktype horses in these recent generations of the family, although not the only ones with triple digit ratings, and it will be fascinating to see how the younger of the pair fares at stud when the time comes.
