Mage Claims Victory in Controversial Kentucky Derby

Mage won the 149th Kentucky Derby by a length, but the race was marred by controversy over the deaths of two horses earlier in the day, following a string of horse deaths earlier in the week at Churchill Downs. The sport is already reeling from a series of doping suspensions and breakdowns. New antidoping and medication rules enforced by a central governing body of the sport are scheduled to take effect May 22.
