Topps was 1 for 4 with the prospects. Kevin Orie was already in the '94 and '96 sets and he'd make another set the next year. Four sets in five years -- they sure were high on him. Brant Brown is most famous from dropping a flyball in 1998 and Pat Cline never reached the majors. The only one of these that really made it was Kerry Wood.
