Mage Claims Victory in Kentucky Derby Amid Controversy.

Mage, a 15-1 shot, won the Kentucky Derby on Saturday, despite only having one win in his career. The race was marred by two more horse fatalities earlier in the day, bringing the total to seven in recent days. Mage's victory was a surprise, but he made a gutsy stretch run to overtake Two Phil's and win by a length. The jockey, Javier Castellano, snapped an 0-for-15 skid in the Derby. The string of horse deaths has raised questions about the future of horse racing, and new antidoping and medication rules are set to take effect on May 22.
