Paulsen was reassigned to minor-league camp Thursday, Rhett Bollinger of MLB.com reports.
Paulsen was hoping to catch on with some reserve at-bats at first base, outfield and designated hitter, but Minnesota instead will stash him at Triple-A Rochester. Byungho Park, who was also sent to the minors, will likely be the first slugger to get the call if the Twins need someone behind Joe Mauer and Kennys Vargas.
