The Royals officially re-signed veteran left-hander Bruce Chen today and they designated infielder Emilio Bonifacio for assignment in order to make room for him on the 40-man roster.

The move is somewhat curious, as the Royals and Bonifacio avoided arbitration two weeks ago by agreeing to a one-year, $3.5 million contract. However, contracts via arbitration are not fully-guaranteed. At the very least, this move means that the Royals have reached their spending limit this winter.
