Chad Tracy. You don’t remember him at all as a Cub, do you?
Tracy had a couple of good seasons for the Diamondbacks in 2005 and 2006, years when they lost 85 and 86 games, respectively. But in 2007, the D-backs won the N.L. West and installed Mark Reynolds at third base, reducing Tracy to being a bench player. After three years of doing that — and not very well — he went to free agency.
He found no takers, until the Cubs signed him to a minor-league contract.
