With three weeks remaining in the 2012 MLB season, the postseason picture is becoming rather clear.
We have a pretty good idea of who the 10 playoff teams will be, though the wild-card race is close enough in both leagues to provide some late-season drama.
However, a handful of teams are fighting for their postseason lives at this point. Those clubs are arguably in that position because their general managers weren't aggressive enough at the trade deadline. Teams that needed starting pitching or a bat in their lineup may be regretting not addressing those holes at the trade deadline.
Here are five general managers who were too passive during baseball's trade season and whose teams could end up paying for that approach as the regular season comes to its end and playoff spots are determined.
(One GM not included on this list is the Detroit Tigers' Dave Dombrowski. Perhaps he should have tried harder to get a bat for left field or designated hitter, such as Alfonso Soriano. But Dombrowski did make one of the bigger moves of the trade deadline, acquiring Omar Infante and Anibal Sanchez from the Miami Marlins.)
All statistics mentioned here are current as of Sept. 10.
