Serbia’s Novak Djokovic has crashed out of the Paris Masters in his first match, losing 0-6 7-6 (7-5) 6-4 to American journeyman Sam Querrey in the second round.
Djokovic, who is assured of finishing at the top of the ATP world rankings at the end of the season, has not lost a match at such an early stage of a competition since Miami in March 2010.
His departure is a fresh blow for the tournament, which has already had to do without star draw absentees Roger Federer and Rafael Nadal.
Djokovic, who regardless of this defeat takes over the world number one spot from Federer on Monday, strode onto the court on Wednesday wearing a Darth Vader mask but found himself the victim of a Halloween horror show.
Querrey fired 18 aces in a battle lasting just over two hours, with the American winning his first career match against a top three player after nine defeats.
Djokovic had said this week the lack of a rest week prior to the season-ending World Tour Finals, which begin in London on Monday, could have repercussions, though barely imagining that he could be the week’s first major victim.
The Serb had said he was trying to conserve his strength for the final competitive sprint – even in a season shortened by a fortnight.
Wednesday’s shock win was the first for the 23rd-ranked Querrey against Djokovic.
Djokovic, who had not played since beating Andy Murray for the Shanghai title to win two Asian trophies in subsequent weeks last month, found his win streak stopped on 10.
The last two places in the London field will be decided this week in Paris, with Jo-Wilfried Tsonga the next qualification candidate.
He heads Serb Janko Tipsarevic, who kept his hopes alive as he reached the third round at the Bercy arena beating Dutchman Igor Sijsling 6-4 7-6 (7-0).
French 12th seed Richard Gasquet lost his chance to continue on pace for the year-end event as he went down in the second round to South African Kevin Anderson 7-6 (7-5) 4-6 6-1.
Provisional London 12th man Juan Monaco of Argentina bolstered his long-odds hopes with a 7-6 (7-4) 6-2 defeat of Bulgarian Grigor Dimitrov.
