This isn't a real "contest" but I was just thinking that many current or past Puerto Ricans have/hadnicknames. For example:

Alex "El Nene" Sanchez
Ivan "Iron Boy" Calderon
Felix "Tito" Trinidad"
Hector "Macho" Camacho
John "The Quiet Man" Ruiz
Carlos "El Indio" Quintana
Kermit "The Killer" Cintron
Wilfredo "Bazooka" Gomez

If you could give Cotto a nickname, what would it be?
