>The Arizona Diamondbacks, tired of playing to their potential, fired their GM Josh Byrnes and their manager A.J. Hinch last week.  Byrnes signed an 8-year extension following the 2007 season, and Hinch took over for Bob Melvin in May, in spite of the fact that he had absolutely no managerial experience.

Now, typically, if you are hiring a guy with absolutely no managerial experience on any level, you aren’t expecting to win right away.  It is a long-term commitment.  Apparently, the front office in Phoenix considers 13 months to be “long term.”
