LONDON (AP) Novak Djokovic overcame an illness - and Alexander Zverev - to earn a second straight win at the ATP Finals.
Despite requiring a tissue to blow his nose between points, Djokovic beat Zverev 6-4, 6-1 on Wednesday to close in on a spot in the semifinals at the season-ending tournament.
"Unfortunately today hasn't been great in terms of that (illness)," Djokovic said. "Somehow I managed to gather the strength when I needed it."
