Fleer's first Update set since 1994 is this 100-card boxed set. It arrived soon after the conclusion of the 1998 World Series and focused on rookies who made their major league debut in September and had not yet had a rookie card. The set had 70 rookies, including 15 making their major league debut, 20 traded players and free agents. There was one subset called Season's Highlights that focused on feats like Mark McGwire's 70th home run, Sammy Sosa's single-month home run record and Kerry Wood's 20 strikeout performance. - 2007 Standard Catalog of Baseball Cards, 16th Edition.
