Rauch traded to Arizona

Recently the Washington Nationals traded Jon Rauch to the Arizona Diamondbacks receiving mediocre prospect Emilio Bonifacio in exchange.  Emilio was give a C+ rating heading into the season by John Sickles and has had a good year at the age of 23, but this being in the PCL.  Meanwhile Jon Rauch over the last two seasons has been outstanding striking out 117 in 136 2/3 innings while only walking 28 posting WHIPs under 1.1.  

My question to you is, did the Twins miss the Rauch-train?  Do you think the Twins should have tried to acquire him if we would to have given up say Valencia, Hughes, or Plouffe?

I personally believe this was a great trade for Arizona giving up a future utility infielder for a very dependable arm in the bullpen.
