Justify's victory in Saturday's Kentucky Derby was worth $1.432 million to the horse's owners -- and nearly as much to one Texas woman who picked five straight winners in Races 8-12 at Churchill Downs.

Margaret Reid, from Austin, won $1.2 million with her $18 Pick 5 bet, placed almost 1,100 miles away, at Retama Park, in Selma, Texas.

Justify, going off at 3-1, had the surest odds of the winners chosen by Reid, who wasn't afraid to go with the long shot in the 10th race of the day, scoring with Funny Duck at 40-1 in the Pat Day Mile.

"To bet that little amount of money and win $1.2 million is unheard of. In fact, it's the first time it's happened at Retama," track spokesperson Rachel Bagnetto told ABC News.

Reid also picked the winners in the eighth (Limousine Liberal, 4-1), ninth (Maraud, 8-1) and 11th (Yoshida, 10-1) races.
