Anything could happen but I wonder if it would be worth putting ESPN Deportes on 890/1400; if reg ESPN didn't work there why would the Spanish version do so, unless the Spanish speaking population really is into sports and would appreciate a national perspective service in that language. Who knows, could happen. I do know that the Red Sox like many teams do feature their broadcasts in Spanish
The following page lists Red Sox in Spanish on 5 stations, in the cities of Boston, Haverhill, Webster, Bristol CT,
and down in RI

But if no sports in Spanish on 890/1400 who knows what could go there.
