The Cubs, realizing that the availability of sluggers in future free-agent markets is small, are pursuing both Prince Fielder and Albert Pujols, according to Major League sources. Pujols is almost four years older than Fielder, but Chicago is willing to give the long-time Cardinal a long-term deal because of his superior defense and Fielder's weight. Chicago's goal of rebuilding through the draft took a hit in the new collective bargaining agreement, which will penalize teams that spend over set limits on amateurs. Clubs that exceed the limits will be subject to taxes and the loss of top picks.
