Sam Querrey recovered from a humiliating first set to beat second-seeded Novak Djokovic 0-6, 7-6 (5), 6-4 in the second round of the Paris Masters on Wednesday.
It was the first time since the Miami Masters in March 2010 that Djokovic has been eliminated so early in a tournament.
"During the second set, I already felt that physically I'm down, and I struggled [in] every game," Djokovic said. "It's unfortunate, but on the brighter side, I have a little bit more time to rest, because I had really difficult period in the last couple of weeks. Some things happened and a lot of things on my mind."
The Serb entered the court wearing a Darth Vader mask on Halloween, and continued to put on a show by winning the first set in just 21 minutes.
"It was a little embarrassing," Querrey said. "But then I got rolling and got more confidence and started serving better and being a little more aggressive."
Djokovic then started to waver under the relentless accuracy of the American's big serve, and made too many unforced errors the rest of the way.
Querrey hit 18 aces and converted his second match point when Djokovic's return sailed long.
Querrey will play 14thseeded Milos Raonic of Thornhill, Ont., in the third round. The hard-serving Canadian had 26 aces in a 6-7 (4), 7-6 (4), 6-3 win against Jeremy Chardy of France.
