I think K-Rod would get the first shot at closing, wouldn't be a bad idea to flip him with Ax, just to take a little pressure off Ax, I don't think he's been bad enough to be sent to the minors at this point.
Probably time to stop giving Veras important innings, his numbers are absolutly terrible (though he has held 7 leads along with a save with only one blown save). Still, a WHIP north of 1.80 and a BB/9 rate over 6, not a guy we need to have in there in close games. Might as well use Loe/Parra/Dillard/Hernandez before him.
I think it's time to really start looking at other options for the bullpen, make a waiver claim or two, bring up minor leaguers, just anything. In 2010 after a few months of terrible bullpen work 5 of the orginal 7 were already gone. Guys like Braddock, Axford, and Parra got chances and did pretty well. The same needs to be done this season.
