I think there is pressure sometimes on managers, etc because if you have an established closer who you are paying a bazillion dollars ... the casual fan base and others will expect that guy to be in there to finish games and, in theory, that guy should be your most dominant reliever so your trust to put him in there is constant. HOWEVER With Knebel out this is a great experiment and I love that it has happened twice in a row now. The Brewers have multiple guys who can be dominant on a given night (Hader, JJ, Barnes, etc) As was mentioned above, if one of them comes in in the 8th and is throwing well (in theory that means he didn't throw a lot of pitches to get through the inning) ... don't burn another 'good' arm in the 9th. Let the guy finish and save the pen a bit. I love the thought. Let's see if the practice proves the theory.
