Many professional baseball players don’t want their first name used when referring to them. Instead they go by a middle name or a short form like J.P. or A.J. or C.C. Some players even legally change their name. This name change is done for different reasons. A perfect example is Los Angeles Angels pitcher Ervin Santana’s real name is Johan Santana. Ervin changed to Ervin because of the New York Mets pitcher Johan Santana who was already playing in the MLB. He did this so commentators, fans and players would not get mixed up and confused. Many players named Michael or Matthew or Alexander, have the choice to go by Mike or Matt or Alex. I have made a list of the current MLB players who have a short-form name or have changed their name.
