What in the world is going on with the NL closers this year? Every team seems to be having severe problems with these guys. As recently mentioned on these pages, Danny Kolb has been horrendous. But what about Mota on the DL? And Benitez. And Tsao (although its a good career move for a closer to go on the DL until traded from Colorado). And look at the Cubs troubles with Hawkins and Dempster, et al.
What is going on with the ranks of the closers? Is it poor conditioning? Over-use? Lack of steriods? Maybe complete game pitcher will make a comeback this season. Out of pure necessity.

Danny Graves also fits into the “healthy but terrible” column. Part of it, I think, is that although several of these guys have been anointed “closers”, they’re not really great pitchers. They’ve just hung around long enough to be given a shot at closing, and if they’re halfway decent they become the incumbent. And you know how hard it is in today’s climate to unseat an incumbent…

Update:
Former Cubbie closer Joe Borowski was activated from the 15-day disabled list today.
