Which says more about WAR than it does about Gore.
the game, who was almost exclusively used as a pinch runner (and thus almost exclusively asked to do something for which he was better than almost everyone else in the league) proved himself marginally more valuable than a AAA player? If we treated his career performance as one year of production, it would take one of the best baserunners in the game 10 years before he proved himself one full win over a replacement level player. That would likely understate his value--not overstate it.
I haven’t seen any more specifics beyond that.
Memorable Cubs moment was pinch running in the 8th in the 2018 wild card game against the Rockies, stealing 2nd, and scoring the tying run - unfortunately the Cubs only run of the game. Then he was forced into hitting twice in extras due to an empty bench and struck out both times. Second AB leading off the bottom of the 13th down by one run, he worked a full count before chasing a pitch well out of the zone to strike out.
My memory of the above was foggy - I went back and looked it up.
Very sad to see him go. Seemed like he played the game with a lot of joy and made the most of his limited skills.
