After dropping the opening set at love, American Sam Querrey charged back to stun Novak Djokovic at the $3.15 million BNP Paribas Masters, the final ATP World Tour Masters 1000 tournament of the year.

Querrey managed to win only 10 points in a 20-minute first set before fighting back for an unlikely 0-6, 7-6 (7-5), 6-4 victory at Bercy's Palais Omnisports. The second-seeded Djokovic actually led 6-0, 2-0 before Querrey mounted his comeback in a 2-hour, 1-minute affair.

The 23rd-ranked Querrey fired 18 aces and was broken only once in the upset of the 2009 Paris Masters champion Djokovic, who was this year's Australian Open winner and French and U.S. Open runner-up.

This marks Djokovic's earliest exit since 2010.

Djokovic learned on Monday that he will finish as the year-end No. 1 for a second straight year. He will supplant current No. 1 Roger Federer atop the rankings next week. Federer pulled out of this Paris event Sunday night after losing to Juan Martin del Potro in the finale at the Swiss Indoors Basel.

Fourth-seeded David Ferrer avoided an upset by leveling fellow Spaniard Marcel Granollers 6-1, 6-3. The six-time 2012 ATP champion Ferrer is fresh off his title in Valencia in his native Spain last week.

French wild card Michael Llodra moved on by upsetting 10th-seeded American John Isner 6-4, 7-6 (7-5). Isner fell despite striking 15 aces, but he also had his serve broken once while failing to break the veteran left-hander Llodra.

Meanwhile, eighth-seeded Serb Janko Tipsarevic topped Dutch qualifier Igor Sijsling 6-4, 7-6 (7-0), ninth-seeded Argentine Juan Monaco got past Bulgarian qualifier Grigor Dimitrov 7-6 (7-4), 6-2, and 11th-seeded Nicolas Almagro outlasted fellow Spaniard Albert Ramos 7-6 (7-1), 6-7 (4-7), 6-3.

Also on Day 3, South African Kevin Anderson upended 12th-seeded Frenchman Richard Gasquet 7-6 (7-5), 4-6, 6-1 and France's Gilles Simon bested Romanian lucky-loser Victor Hanescu 7-5, 6-3. Hanescu replaced last year's Paris Masters champion Federer in the draw.

The newest Paris Masters champ will pocket $620,000.
