Bred by Haras Marovi S.A., Inconmensurable is by Cosmic Trigger, who won two 1600-meter races at Palermo before ending his racing career prematurely. A muscular, heavy-topped, rather light-boned horse, he got his chance at stud partly on displayed talent and partly on his standing as a half brother to the brilliant champion Candy Ride, a highly successful Kentucky stallion who has ranked six times among the top 10 American sires.
A rising star in the Argentine stallion ranks (he is currently third on the Argentine general sire list), Cosmic Trigger has gained a reputation for siring precocious speed while standing at Haras Abolengo. This is in keeping with his male line, as he is by 2009 Railway Stakes (IRE-G2) winner Lizard Island, by 1995 Irish champion 2-year-old male Danehill Dancer, by the great Australian/European sire Danehill.
On the distaff side of her pedigree, Inconmensurable is a fourth-generation descendant of 1985 Breeders’ Cup Juvenile Fillies (USA-G1) winner Twilight Ridge. Sired by 1978 Metropolitan Handicap (USA-G1) winner and good sire Cox’s Ridge, Twilight Ridge is out of Waving Sky, by Fred Hooper’s Argentine import Quibu (a major stakes winner in Argentina and Uruguay) out of a half sister to Hooper’s good racehorse and sire Tri Jet. She was generally considered the second-best American 2-year-old filly of 1986 behind champion Family Style but failed to train on as well as hoped and dropped out of sight after running second in the 1986 Santa Anita Oaks (USA-G1), although she continued racing through age 4.
Twilight Ridge was a successful broodmare, producing 1995 Demoiselle Stakes (USA-G2) winner La Rosa (by Wild Again) and listed stakes winner Daylight Ridge (by Dayjur). La Rosa, in turn, produced multiple Group 2 winner Le Bernardin (by Bernardini) and 2006 Sabin Handicap (USA-G3) winner Taittinger Rose (by Menifee), while Daylight Ridge produced multiple listed stakes winner Independent George (by Cozzene). Another daughter of Twilight Ridge, the Storm Cat mare Itsmylife, produced Revenant One (by Macho Uno), an Indiana-bred restricted stakes winner.
In Twilight, a 1989 daughter of Twilight Ridge by In Reality, never raced and produced only three winners from her 12 foals, the best of which was listed stakes-placed Askara (by Private Terms). Her 1999 daughter Lady Manolo (by Meadowlake) likewise never raced and produced five winners from eight named foals. Among those winners was Mint Brownie, a 2006 Salt Lake filly who won one of her three starts before being exported to Argentina, where she has produced four winners from nine foals. Inconmensurable is much the best of the four, but Mint Brownie also has Group 2-placed China de Arteaga (by Aussie Rules) and Michonne Trigger (by Cosmic Trigger) to her credit. Her only foal since Inconmensurable is a 2024 colt by the stakes-winning Candy Ride horse Reride that has already been named Lusail Lake.
Given the history of both her sire and of the first three generations of her dam line, the question may well be how long Inconmensurable can remain sound. Her full sister Michonne Trigger lasted only six starts, although she won four in addition to her Group 2 placing, and this is not particularly encouraging in hoping for more than a brief career for what is clearly a highly talented filly. But if Inconmensurable can keep four good legs under her, she may well prove that her name is a good reflection of her ability.
