Nancy, France ( - Germany got a pair of upset wins Friday, including one by little-known Peter Gojowczyk over French star Jo-Wilfried, as the visitors grabbed a stunning 2-0 lead in a best-of-five Davis Cup quarterfinal on an indoor hardcourt in Nancy.

The Day 1 nightcap saw the world No. 119 Gojowczyk defeat the 12th-ranked Tsonga, 5-7, 7-6 (7-3), 3-6, 7-6 (10-8), 8-6, in 4 hours, 19 minutes.

Gojowczyk saved two match points in the fourth set before converting on his third match point in the fifth when the former Australian Open runner-up Tsonga netted one final forehand to deflate stunned French onlookers at Palais Des Sports Jean Weille.

The 24-year-old Gojowczyk, who picked up his first ATP match win in Doha just over three months ago, overcame a leg cramp in the final set in a memorable Davis Cup debut on Friday.

Tsonga crushed 36 aces in a losing effort, while Gojowczyk struck 21. The German tallied only service break, which turned out to be a huge match-ending one.

In Friday's opener, Tobias Kamke took down world No. 50 Frenchman Julien Benneteau in straight sets, 7-6 (10-8), 6-3, 6-2.

The undermanned Germans are competing without any of their top-six players. Their top performer this week, Kamke, is ranked 96th in the world.

Saturday's doubles in Nancy will pit a French team of Michael Llodra and Gael Monfils versus a German tandem of Kamke and Andre Begemann, while Sunday's reverse doubles will see the former Australian Open runner-up Tsonga facing Kamke and Benneteau battling Gojowczyk.

Team France is led by rookie captain Arnaud Clement, while the Germans are guided by Carsten Arriens.

The French are 7-2 all-time versus the Germans, including a win in their last meeting in a quarterfinal in Stuttgart in 2011. They first met in 1913, with Germany winning that one in Wiesbaden.

The winner in Nancy will meet the Czech Republic-Japan victor in a semifinal in September.
