Stat of the Day: Novak Djokovic now 31-0 in first two rounds of US Open
The 20-time Grand Slam champion has never lost before the third round in 16 career appearances in New York.

Novak Djokovic is still perfect in the first two rounds of the US Open, thanks to a 6-2, 6-3, 6-2 win in the second round on Thursday night against Tallon Griekspoor.
The Serb improved to 16-0 in first-round matches in Flushing Meadows with his 6-1, 6-7 (5), 6-2, 6-1 victory over Danish teenager Holger Rune on Tuesday night, and to 15-0 in second-round matches with his win over Dutchman Griekspoor.
The second-round record doesn’t include a walkover against Jiri Vesely in 2016.
On Thursday, the Serb hit 33 winners to 20 unforced errors to cruise past the 25-year-old Griekspoor in an hour and 39 minutes on Arthur Ashe Stadium.
“Great performance. Better, definitely, than the first-round match,” Djokovic said afterwards. “Obviously I’m very pleased with the way I came out on the court. I served very well. I found the rhythm on the serve. It was important I came up with the goods.”
Up next for Djokovic is Kei Nishikori, who he’s beaten the last 16 times they’ve played.
