VIENNA (AP) — Novak Djokovic saved four set points in a 7-6 (11), 6-3 win over Borna Coric on Wednesday to reach the Erste Bank Open quarterfinals and move one step closer to sealing the year-end No. 1 ranking.
Djokovic can lock up the top position by winning the title on Sunday.
Otherwise Rafael Nadal could still mathematically overtake him, although the Spaniard would need to enter a tournament in Bulgaria next month in order to do so.
Djokovic will play either Hubert Hurkacz or Lorenzo Sonego in Friday’s quarterfinal.
