Novak Djokovic refused to discuss an evident eye problem he suffered before Sunday’s Miami Open final defeat to unseeded Czech teenager Jakub Mensik, 19, saying he did not want to take away from his opponent’s triumph.

After a near-six hour rain delay, Djokovic appeared with what looked to be a stye causing swelling around his right eye. He made a slow start, dropping his first service game before losing 6-7 (7/4), 6-7 (7/4).
