I briefly worked with a guy who was from Puerto Rico... and he sometimes wore a hat with this logo into work on casual Fridays...
The team name is Cangrejeros de Santurce... and if my recollection of high school Spanish servers me correctly.. cangrejo is a crab and a cangrejeros is a man who gets crabs. Whoa... that sounded bad... ummm whatever the term is in English for a fisherman who catches crabs. Damn.. that did not make things any better... Anyways, you get the idea. Always loved the logo... so there is my suggestion. No idea how old this actual team is or if it existed during the time of your historical sim... I know PR baseball has been around forever.
