Back in 2007, Jason Kendall played 57 games for the Cubs. He came over from Oakland in a midseason trade and provided some offensive stability as a catcher for the Cubs during their playoff push. While his time in Chicago was short-lived–he left town via free agency that winter–Kendall made an impact during his short time, as he did in longer stints for Pittsburgh and Oakland.
Similar remarks could be offered for Mark Grudzielanek–one of Harry Caray’s favorite players–who helped the ’03 Cubs.
It’s safe to say that while these players made big contributions during their careers, they are not Hall-bound.
