Any of them just as much as Estrada, but that's not the point. Getting runs right there has much more value than stretching out 1 more inning out of your 6th starter who probably just started taking actual BP a week or so ago on his first start. If you have arms in the pen you need to use them, the 'who do you have confidence in?' line isn't even applicable, they are in our pen for a reason - do you have confidence in Estrada? B/c I have just as much confidence in them as I do in him going into the 6th inning.
