This is a list of people currently serving in the role of general manager (GM) for the 30 teams of Major League Baseball (MLB).
Several of these general managers operate with the titles of "president of baseball operations" (or variants thereof, such as "chief baseball officer") in addition to, or in lieu of, a general manager title. Others, while maintaining the title of general manager, are subordinate to presidents of baseball operations who have final authority on team personnel decisions.
For example, St. Louis Cardinals GM Mike Girsch reports to former GM and current president of baseball operations Chaim Bloom. Similar relationships appear to exist in Minnesota Twins (Jeremy Zoll to Derek Falvey), Cleveland Guardians (Mike Chernoff to Chris Antonetti), Philadelphia Phillies (Preston Mattingly to Dave Dombrowski), the Los Angeles Dodgers (Brandon Gomes to Andrew Friedman), the San Francisco Giants (Zack Minasian to Buster Posey), the Seattle Mariners (Justin Hollander to Jerry Dipoto), the Miami Marlins (Gabe Kapler to Peter Bendix), the Chicago Cubs (Carter Hawkins to Jed Hoyer), the Tampa Bay Rays (the role, while currently vacant, reports to Erik Neander), the Washington Nationals (Anirudh Kilambi reports to Paul Toboni), and the Colorado Rockies (Josh Byrnes to Paul DePodesta) Responsibilities with the Toronto Blue Jays (Ross Atkins and Mark Shapiro) are less clear in terms of who holds the highest authority.
