A P Valentine, a Grade 1 winner and runner-up in the 2001 Preakness and Belmont Stakes, has been pensioned to Old Friends Equine Retirement in Georgetown, Ky., along with Grade 3 winner River Squall.

Nicanor, a stakes-placed runner, sire, and full brother to Kentucky Derby winner Barbaro, has been pensioned to Old Friends Equine Retirement in Georgetown, Ky.

The 12-year-old son of Dynaformer gained a following as the first sibling of Barbaro’s to reach the racetrack after Barbaro died from complications tied to his breakdown in the 2006 Preakness Stakes.

Afleet Again, the longshot winner of the 2011 Breeders’ Cup Marathon, died in Korea on April 12 after a bout of colic. He was 11.
