Another factor in this decision has to be what has happened to relief pitchers in the Twins system. Oliveros seems to have flamed out (injured now?) at AAA, Achter is a soft-tosser and Tonkin seems to be good at AAA, but has failed in his chances in MInnesota. At Chattanooga, the vaunted big arms of Reed, Burdi, and Zach Jones have flamed out, at least for now. A couple of starters may be moved to the bullpen, or maybe already should be there, but guys with a chance because of strikeout ability and high K rates haven't progressed as expected. Having Jepsen both this year and next, seems to be an OK move. Giving up a couple of decent arms in A ball isn't terrible. It seems that Hu has overperformed his stuff, but it is questionable that he can move all the way to the majors and thrive.
