Background

Bred and owned by William T. Young's Overbrook Farm, Grindstone was the son of Unbridled out of the mare Buzz My Bell. Buzz My Bell's dam was a half-sister to La Grue, the dam of the Belmont Stakes winner Pass Catcher.
Racing career
Prior to the Derby, Grindstone had won the Louisiana Derby and was second in the Arkansas Derby.

Grindstone was retired just 5 days after his Kentucky Derby victory when knee chips were discovered in his leg. He is the first horse since Bubbling Over in 1926 to be retired immediately following a win in the Kentucky Derby.
Stud record

He stands today at Oakhurst Farm in Oregon (making him the first Kentucky Derby winner to ever stand in the Northwest). His progeny include two millionaires, GR I winner Birdstone and Ekolu Place. He is also, via Birdstone, the grandsire of Mine That Bird and Summer Bird, who both won Triple Crown races in 2009.
