Dan O'Brien was fired yesterday as the general manager of the Reds. Such are the hazards of a GM in a losing club when that club has a new owner.

O'Brien's tenure as the Reds GM can be best summed up with what he did with overrated fan favorite Sean Casey this offseason. First, he picked up Casey's $8.5M option for 2006 in October, only to trade him to the Pirates in December. Odd. If you can find some logic in such maneuvering, explain it to O'Brien.

Anyway, O'Brien should be used to getting fired: it's in his genes. His dad, Dan O'Brien as well, was fired by three clubs (the Rangers, Mariners, and Angels), and Dan II can take some solace in the fact that his poor record with the Reds (149-175, .460) is slightly better than Dan I's career record with those three franchises (644-767, .456).

It does, however, leave just one active baseball GM who is the son of another GM, Bill Bavasi of the M's. That made me wonder what the overall record was for all of the GM families that baseball has seen over the years.

First, we have to establish what those GM families are. I found the following: The Bavasis (Buzzie, Bill, and Peter), the O'Briens (Dan I and Dan II), the Smiths (Tal and Randy), the McHales (John J. and John), the Quinns (Bob I, John, and Bob II), and the McPhails (Larry, Lee, and Andy).

Here are there career totals as individuals:

Now the totals per family:

And there you have it. The O'Brien clan is the worst of the bunch, by percentage or win total. It's not every day that someone can surpass Randy Smith in bad GM'ing. Dan II can be proud.
