The Chicago Cubs acquired right-handed reliever Kevin Gregg from the Florida Marlins on Thursday, a move than means closer Kerry Wood won't return.
Wood, the 1998 NL Rookie of the Year who saved 34 games this year, had been the longest-tenured player on the Cubs.
General manager Jim Hendry said Wood was deserving of a three- or four-year deal and the Cubs are not prepared to offer him one.
