Novak Djokovic overcame an early scare to reach the third round of the US Open on Wednesday as defending women's champion Aryna Sabalenka prepared to step up her title bid.
Djokovic, who is chasing a record 25th Grand Slam singles title, recovered from going a set down against American qualifier Zachary Svajda to complete a 6-7 (5/7), 6-3, 6-3, 6-1 win on the Arthur Ashe Stadium Court.
