As several people have pointed out, there are other setup otions besides Eyre and Howry. There are 3 bloody lefties in the pen, along with 2 options in AAA. There are 2 perfectly acceptable RH setup options in Marmol and Wuertz that you can use before Howry, and a couple more in AAA and AA that you can use. There's no good reason to justify this lunacy. Maybe Piniella ought to learn from his own mistakes and not put those two gascans in a position to blow games until they fix their issues, instead of crippling his starting rotation. For the most part, Piniella has stopped using Eyre. Only 6 appearances since April 24th, and half of those were either blowouts (the 9th inning of a 7-1 win or a 10-1 win) or extra innings after most everybody else had pitched. So, then, why call up Marmol and then demote Guzman to the pen? All on account of Howry? That's stupid. You don't need to hurt two guys in order to hide one. If they plan on Marmol starting, they're stupid. If they demote him just so Marshall can pitch, they're equally stupid, because Marshall is not going to be better than Guzman, has a good chance to be worse, and Marmol would be better suited to relief than Guzman would be anyway. This move can't be justified any way you look at it.
