Baseball changes are incremental. Teams usually like to see if something works for them, before instituting the change across the board. Pitching used to be about the starting pitcher almost exclusively. Then, the closer became important. Now, the term Opener is getting into vogue. Would you be in favor of the Cubs experimenting with an Opener?
My introduction to the opening pitcher debate goes to Wayne Randazzo. Now with the New York Mets gameday crew, he used to call games for the Kane County Cougars when they were a Cubs affiliate. He noticed that when a MLB pitcher was on rehab, however he did, the primary reliever behind him would often have a rather decent outing.
