Time for a pitching change?

Konnichiwa (that's Japanese for good afternoon). ... Chad Billingsley hasn't allowed a run in his past 9 2/3 innings, the result of a mechanical tweak he worked on with bullpen coach Dan Warthen three weeks ago. Given that he is a natural starter, and given that club officials have always said he eventually will go back to starting, Billingsley might be a good candidate to replace Brett Tomko in the next couple of weeks if Tomko continues to suffer from the same inconsistency that has plagued him all season. On the other hand, as good as this bullpen is, it would be tough to take someone as reliable as Billingsley out of it right now. My guess is this is on Grady Little's mind, but he isn't ready to pull the trigger on it just yet. Give Tomko a little more rope, and it might become a no-brainer decision that wouldn't ruffle any feathers. Do it now, when there is at least some room for disagreement, and it's a controversial move.
