While researching my book "everycubever" (https://eckhartzpress.com/shop/everycubever/), I did a deep dive into all-star game history to see which Cub did what.
There have been 89 All-Star games, but only three Cubs have stolen a base in an All-Star game. Starlin Castro has the all-time Cubs record with two. Derrek Lee (2007) and Ryne Sandberg (1984) are the other two, and they both only did it once.
