This is a list not of the 50 best players in MLB — Buster Posey is no longer one of the best hitters in our sport — but, rather, of the top 50 people set to influence the 2025 MLB season. Think of these individuals as the predominant characters in your favorite TV show, with the season premiere airing on Thursday.
On this list are All-Stars, prospects and some players you’ve maybe never heard of, as well as owners, managers, front-office execs and four guys named Jackson (that's one more than last year).
The hope is that this list helps you sort out what to know and whom to care about as the 2025 MLB season begins.
