The top-ranked Djokovic faced a potentially tricky second-round matchup Wednesday against Jiri Vesely, who defeated him in their only meeting last spring. But Vesely pulled out of the tournament with left forearm inflammation a couple of hours before their match would have started.
The 2015 U.S. Open runner-up, Roberta Vinci, cruised into the third round for the sixth straight year.
The seventh-seeded Italian beat American Christina McHale 6-1, 6-3 on Wednesday. Vinci needed just 22 minutes to win the first set.
The 55th-ranked McHale was trying to reach the third round at the U.S. Open for the third time.
Vinci stunned Serena Williams in last year's semifinals to thwart her bid for the first Grand Slam since 1988, then lost to countrywoman Flavia Pennetta in the final.
