SHANGHAI — Novak Djokovic extended his winning streak to 13 straight matches with a swift 6-2, 6-1 win over Martin Klizan in the second round of the Shanghai Masters on Wednesday.
Rafael Nadal also advanced to the third round, although in far more difficult fashion. The eighth-seeded Spanish player escaped with a 7-5, 6-7 (4), 7-6 (4) win over Ivo Karlovic of Croatia in two hours, 43 minutes.
Djokovic is coming off his sixth China Open title last week, where he only lost 18 games in the entire tournament — the most dominant title run of his career.
