Examining the history of an MLB GM can be essential for research or informed speculation. The problem? There’s never been one place to easily reference each GM’s tenure…until now.
I’m proud to introduce our new MLB GM Tracker, a simple yet powerful tool for Trade Rumors Front Office subscribers that displays each team’s GM dating back to the year 2000. To the best of our ability, we’ve compiled start and end dates for every GM during that period, including those who served in an interim capacity. You can learn more about Trade Rumors Front Office here.
The MLB GM Tracker allows you to search by name and filter by team, narrow to current GMs, and filter and sort by the number of active days. At the moment, MLB GM tenures range from Buster Posey’s 115 days to Brian Cashman’s 9,851 days on the job.
One note: for this tool, we’re using “GM” as an umbrella term to mean the team’s top decision-maker in baseball operations. Many of these people hold the title of “president of baseball operations” or something similar.
Here’s a look at the team level:
We’ve connected the MLB GM Tracker to our robust MLB Contract Tracker as well. Clicking the GM’s name in the GM tracker takes you to his entire tenure with that team, within the Contract Tracker. Here’s Matt Klentak:
When you’re in the Contract Tracker, which currently goes back to 10-1-08, you can filter to any GM and adjust the date range to see that GM’s work across different teams. Here are Alex Anthopoulos’s biggest deals across the Braves and Blue Jays:

Also, David Forst’s tenure with the A’s had to be broken up into two separate entries due to the team changing its name.
