Melbourne, Jan. 24 -- Novak Djokovic made more history in Melbourne on Saturday, becoming the first player ever to reach 400 Grand Slam singles wins, as he advanced to the fourth round of the Australian Open for an 18th time.

The 38-year-old fourth seed defeated Dutchman Botic van de Zandschulp 6-3, 6-4, 7-6(4) under the Rod Laver Arena roof. Djokovic enjoyed a strong start but faced moments of tension in the second and third sets, including saving two set points late in the third.

With the win, Djokovic moved to 102 career victories at Melbourne Park, equaling Roger Federer's record at the tournament. Despite the scoreline, he admitted to feeling pressure at times and took a medical time out for foot treatment.
