LOUISVILLE, Ky. (AP) — After seven deaths raised questions about the future of horse racing, Mage earned a surprising Kentucky Derby victory on Saturday, capping a nerve-rattling day that included two more fatalities ahead of the 149th edition of the world’s most famous race.

Mage, a 15-1 shot, had only one win in his career, giving little indication that he could triumph against 17 rivals in a race that is not kind to the inexperienced.

Still, he made a gutsy stretch run, overtaking Two Phil’s to his inside and winning by a length. Mage, who didn’t race as a 2-year-old, ran 1 1/4 miles in 2:01.57.

Mage joined Justify (2018), Big Brown (2008) and Regret (2015) as Derby winners with just three previous starts.

“He proved today that it didn’t matter,” assistant trainer and co-owner Gustavo Delgado Jr. said.
