Tests prove top finishers at Kentucky Derby and Oaks were clean of steroids

No positive steroid test at Derby, Oaks

LEXINGTON, Ky. — Kentucky racing officials say no horse tested positive for steroids or other banned drugs at the Kentucky Derby or Kentucky Oaks.

This is the first year the post-race testing at Churchill Downs screened for anabolic steroids.

The Kentucky Horse Racing Commission says blood and urine samples analyzed at a University of Florida lab are negative. The top four finishers in both races were tested, including Derby winner Mine That Bird and Oaks winner Rachel Alexandra.
