Baseball’s Longest-Tenured GMs

Ever wonder which GMs have held their positions the longest? Or how many GMs were with their current teams a decade ago? I've compiled the list thanks to Baseball America's executive database. It shows how long GMs have been with their current teams, not when they got their first gig running a team. That list would look different, with Andy MacPhail, Dave Dombrowski and Sandy Alderson at the top (I'm using the term 'GM' loosely; some of the executives below have different titles on their business cards). 

The Bay Area has baseball's two longest-tenured GMs, two of the five people on this list to have held their current job for more than a decade. There's been lots of turnover in the past five years, as more than half (17) of baseball's GMs were hired in that time. Here's the complete list:

  1. Brian Sabean, Giants, 1996
  2. Billy Beane, Athletics, 1997
  3. Brian Cashman, Yankees, 1998
  4. Dan O'Dowd, Rockies, 1999
  5. Kenny Williams, White Sox, 2000
  6. Larry Beinfest, Marlins, 2002
  7. Dave Dombrowski, Tigers, 2002
  8. Jim Hendry, Cubs, 2002
  9. Doug Melvin, Brewers, 2002
  10. Theo Epstein, Red Sox, 2002
  11. Jon Daniels, Rangers, 2005
  12. Andrew Friedman, Rays, 2005
  13. Ned Colletti, Dodgers, 2005
  14. Dayton Moore, Royals, 2006
  15. Andy MacPhail, Orioles, 2007
  16. Bill Smith, Twins, 2007
  17. Ed Wade, Astros, 2007
  18. Neal Huntington, Pirates, 2007
  19. Frank Wren, Braves, 2007
  20. Tony Reagins, Angels, 2007
  21. John Mozeliak, Cardinals, 2007
  22. Walt Jocketty, Reds, 2008
  23. Jack Zduriencik, Mariners, 2008
  24. Ruben Amaro, Jr., Phillies, 2008
  25. Mike Rizzo, Nationals, 2009
  26. Alex Anthopoulos, Blue Jays, 2009
  27. Jed Hoyer, Padres, 2009
  28. Kevin Towers, Diamondbacks, 2010
  29. Chris Antonetti, Indians, 2010
  30. Sandy Alderson, Mets, 2010

wow, almost 10 lovable losing years with old Jimmy Hendry…..when are they gonna learn?

4 years 4 months ago

Hendry’s not the best at drafts, but he does what he’s told (again, the Tribune forced his hand with Soriano) and he’s helped to get the most competitive they’ve been in generations.

4 years 4 months ago

Actually that deal was really made by then Cubs president John McDonough. All Hendry did was follow through on the deal his boss set in place. I don’t blame Hendry for Soriano at all.

4 years 4 months ago

While you can say McDonough wanted Henry to make a “big splash” and get Soriano, Hendry is the one who foolishly gave Soriano an 8 year deal when no one else was offering more than 5.

And McDonough wasn’t around when Hendry gave Milton effing Bradley a 3 year deal.

Hendry is also not the best at signing free agents or making trades . . .

So, I think to myself. Is Larry Beinfest the best GM nobody talks about or knows the name of?

4 years 4 months ago

That was exactly my thoughts! Larry Who?

4 years 4 months ago

balling on a budget!

Michael Hill is their technical GM. Everybody knows who Michael Hill is.

Didn’t Epstein technically step down for a little while there a couple years back? That’d break the tenure, no?

4 years 4 months ago

He did step down, yes. I decided to include him from his start date, since it’s not as though he left to work for another club.

you mean the gorilla suit incident?

Dan O’Dowd is the best on this list. Not only did he turn the rockies into total crap at first, he turned them into a good franchise from essentially nothing (though it did take him a while). He knows how to develop a farm system and turn trash into gold.

He knows how to develop a farm system and turn cheap team-friendly deals into 10 year commitments paid in gold

fixed this for you

any plans to update the GM trade/transaction history series? those were really excellent

4 years 4 months ago

Hmmphhh! No Blacks?

4 years 4 months ago

Kenny Williams…?

4 years 4 months ago

I like to refer to Mike Rizzo as “M to the Rizzo” if that helps.

4 years 4 months ago

tony reagins and kenny williams are confused by your question

4 years 4 months ago

I can’t believe Cashman with the Yankees is the third longest… I thought the Steinbrenners had a reputation to keep up!

I’m not trying to start a death pool here, but which of these guys skates on the thinnest ice at the current moment?

Exactly half of this list was hired in 2007 or later, suggesting that GM’s might get four years at the most to start showing results, or be shown the door.

My money is on Jack Z. He had a number of high profile moves blow up on him in the 2010 off-season. I think he gets one more year to sort through things before the M’s move in another direction.

4 years 4 months ago

Jack Z, Doug Melvin and Dumbrowski. If the Tigers don’t do well this year I’m expecting to see Leyland and Dumbrowski gone. Same thing with Melvin

Double A (AKA the Assassin) was hired by the Jays as head of player development in 2003. They got him after the Nationals(Expos) left Montreal.
Oh yeah…Lunchbox45 is the Jays Travis Snider..who in spite of his early numbers, will have his break out year this season.
