Relievers have always had a checkered history. They are effective for a few years and then something happens and they lose their consistency. There are very few consistent long-time relievers. Therefore, the method the Twins are using to find relievers can work for us. Littell, Duffy, Stewart etc. have had good outings and then are sent down to make room for a fresh arm. From this tactic, the Twins will find effective RP and replacements for the current RP should they become ineffective (Morin)
