Tim Stauffer is not the worst newly acquired relief pitcher for the Twins the last decade, but...

He has Juan Morillo to thank for that (and it is close).   Here is a list of the relief pitchers newly acquired by the Twins who had an xFIP higher than 5, in their first year with the club, during the last 10 years.  The list includes traded players, major league and minor league free agents.

Stauffer has some good company.  (List by decreasing xFIP)
