(NEW YORK TIMES) Newcomers rarely make it into the winner’s circle at the All American Futurity, considered the Kentucky Derby of quarter horse racing.

Yet in September 2010, a beaming band of men waving Mexican flags and miniature piñatas swept into Ruidoso, N.M., to claim the million-dollar prize with a long-shot colt named Mr. Piloto.

Leading the revelry at the track was Mr. Piloto’s owner, José Treviño Morales, 45, a self-described brick mason who had grown up poor in Mexico. Across the border, Ramiro Villarreal, an affable associate who had helped acquire the winning colt, celebrated at a bar with friends.
