Kelli Cruciotti, 17, Wins Grand Prix at Devon.

A week ago, Kelli Cruciotti missed her Skype graduation from online high school because she was riding in a competition. That paid off Thursday night, when the 17-year-old became the youngest winner of the Sapphire Grand Prix at the Devon Horse Show and Country Fair. The Grand Prix dates to 1978.

“I’ve always dreamed about doing a class like this in front of as many people,” Cruciotti said. “To have such a great result is a dream come true.”

Cruciotti, of Elizabeth, Colorado, riding her own Chamonix H, took home the $30,000 price with a time of 38.678 seconds.
