There is a term in English for a tennis player reaching a height, for a brief stretch or longer, when he cannot miss, and tennis people call it zoning .  I have not heard it used in other cases, but when used it seems to equal tener duende .  I do not know whether that use of duende has reached Portuguese speakers in Brazil or Portugal, but if it has not, it probably will soon, because so many Portuguese speakers are bilingual in Spanish.
