Jonathan Sanchez is the newest addition to the Kansas City Royals' starting rotation. He'll join Luke Hochevar, Felipe Paulino and Danny Duffy. The No. 5 spot will go to either free agent Bruce Chen or Luis Mendoza.
The Royals' rotation looks like it was barely touched, compared to some of the teams that are working on their pitching staffs this winter. Many teams are looking for upgrades.
These are nine more teams whose rotations will probably have several changes in it come Opening Day 2012.
