Dominican Kelvin de Leon, 16, who was signed by the New York Yankees for US$1.1 million to join their Major League training academy, warms up during a scrimmage against the Boston Red Sox academy in Boca Chica, east of Santo Domingo, Monday, July 9, 2007. De Leon and Michael Almanzar, two of baseball's hottest Dominican prospects, met as rivals for the first time since receiving massive signing bonuses, cheered by relatives and friends after already achieving the dream of thousands in this baseball-crazed nation.
