By the end of the 1981 season, Bowa had worn out his welcome with the Phillies' front office, and let it be known he was available. The Chicago Cubs, who had just hired former Phillies manager Dallas Green as general manager, quickly expressed interest. However, Green, who had managed the 1980 world champions, knew that Bowa didn't have many years left and demanded a young rookie third baseman named Ryne Sandberg as a part of the trade. In return, the Phillies received shortstop Iván DeJesús. The trade paid off tremendously for the Cubs, as Bowa's veteran leadership and Sandberg's outstanding all-around play (en route to a Hall of Fame career) brought the Cubs to the postseason in for the first time in 39 years.
