Sports history is dotted with brother acts, including the Deans and DiMaggios in baseball, the Spinks in boxing, the Mahres in skiing. But now add to that list the Leone brothers. Pardon?
Indeed, Peter, 22, Mark, 20, and Armand, 25, already have been ranked in this country's Top 10 in horse show jumping, which means little since the sport ranks in visibility just after tortoise racing. The brothers ("We're all pretty good," brags Mark) will attempt this week at the National Horse Show in Madison Square Garden to establish themselves as America's best.
Until recently, celebrity has touched them only because Brooke Shields
boards her two horses for $600 a month at the Leones' Franklin Lakes, N.J. farm.
