David Junior's final race was the Breeders' Cup Classic, which ended in disappointment, as he failed to cope with the dirt at Churchill Downs and finished tailed-off behind Invasor.
Bred by Haras Bage Do Sul at Aceguá, Rio Grande do Sul, he was out of the mare Dissemble and sired by Candy Stripes who also sired Invasor, the horse ranked No.1 in the world for 2006.
