The Giants are one of the teams that only retire the jerseys of Hall of Famers, so while they haven't reissued the number 25 since the all-time home run leader departed San Francisco in 2007, they haven't officially hung it up for good either. Until recently, that appeared to be a major impediment for Bonds, who's beloved by most Giants fans and on good terms with the team (he worked as a special instructor this spring). Due to his connection to performance-enhancing drugs, just 36.2% of BBWAA voters tabbed him when he first became eligible in 2013, and he gained almost no ground over the next two years.
