Yes, I remember the late Joaquín Andújar, former Houston Astros/St. Louis Cardinal/Oakland Athletics pitcher, whose name was usually mangled by baseball commentators. Joaquín sounded like 'Walking' and Andújar life 'Underwear'.@Lucifer
The topic of accentuation and where to put the stress reminds me of English speakers and their incorrect accentuation in Spanish. If you watch a baseball game you hear the incorrect pronunciation in the highest form. All those mispronounced last names of the players is really awful.
Ask an English commentator to say Alcántara, Berríos, Pérez- this has to be the worst pronunciation all over the US, López, Jiménez etc. all wrong
Dominican baseball commentators are just as wrong when pronouncing names of baseball players from the U.S.
The Leones del Escogido, one of two Santo Domingo teams, once had a catcher named Montgomery, but the locals ALWAYS said MontgoMEry.
I know a man who was a big JFK fan since childhood; he named his son Fitzgerald, but they pronounce it FITZgerald.
My better half went to school with a kid named Francois. He gets upset if anyone uses the French pronunciation; he insist that it is FRAN-COIS, the last syllable as in coy: "you don't have to be coy, Roy."
