Rock Hard Ten was a late bloomer and did not race at age two due to shin splints. At age three, he started late in relation to other three-year-olds. Rock Hard Ten stepped up in class four weeks before the Kentucky Derby in the GI Santa Anita Derby and finished second to Castledale but was disqualified and placed third for interference. Due to the late start in the season and his disqualification, Rock Hard Ten did not have enough graded stakes race earnings to qualify for the Kentucky Derby.
