Now I’m curious too. Seattle Slew’s breeder wanted My Charmer to go to Jacinto, another Bold Ruler grandson, but his book was full and Seth Hancock suggested Bold Reasoning instead. But that wasn’t last-minute, at least not by any account I’ve seen.
The story of Signorinetta, a British filly who won both the Epsom Derby and Oaks in 1911, is a quirky one. Her owner bred her dam to the teaser, thinking that because they whinnied to each other when passing that it was a “love match”.
Signorinetta had her crowded hour of fame but never won again. I think it was Lord Derby who bought her as a broodmare and while she wasn’t a standout producer she did okay.
