By the time u wait to see when it's announced he will likely be gone...
Just think logically, Torres is failing in a big way and that he has now lost his job is a given. Torres, has no pedigree as a closer, he just started out well.
Okay, now that that is out of the way. Of the three other potential candidates, who is likely to be the closer? Hmmm lets see, you've already annointed one of your relievers the closer of the future, that same reliever has an ERA and WHIP less than 1, and you have a young team that is not going to win it all at least for a couple of years. Hmmm do u go with Capps? I think so. See, no real need to wait 2-3 days for the team to formally give him the job, you already know they will.
Now between Capps and Soria. Both are unknowns, Capps may get slightly more opportunities with the Pirates so I would go with him.
