Hall of Famer Ryne Sandberg spent 2,164 games in 15 years with the Chicago Cubs, but his first six plate appearances in Major League Baseball came with the Phillies in 1981. The following offseason, the Phillies decided Sandberg couldn't stick at shortstop -- with All-Star Manny Trillo manning second and Hall of Famer Mike Schmidt firmly entrenched at third -- so they traded for their new starting shortstop.
On Jan. 27, 1982, the Phillies shipped Larry Bowa (incumbent shortstop) and Sandberg to the Cubs in exchange for shortstop Ivan de Jesus.
We know the rest. Sandberg went on to become one of baseball's greatest second basemen, racking up 10 All-Star trips, nine Gold Gloves, seven Silver Sluggers and an MVP. De Jesus put together three unimpressive seasons for the Phillies and Trillo was dealt the following offseason as part of a package to land Von Hayes.
