Davydenko crashes out
Fifth seed Nikolay Davydenko suffered an early exit from the Open Sud de France as Jarkko Nieminen booked his place in the quarter-finals.
The Finn was forced into a tie-break as Davydenko survived match point in the second set but Nieminen held on to earn a 6-3 7-6 (10/8) victory in Montpellier, his first win over the Russian in nearly 10 years.
The 31-year-old will face either Sergiy Stakhovsky or Tatsuma Ito in the last eight after the Japanese recovered from a set down to beat France's Edouard Roger-Vasselin 3-6 7-6 (7/5) 7-5.
Roger-Vasselin's countryman Julien Benneteau was leading Adrian Ungur 6-3 4-2 when the Romanian retired hurt in the second set and Arnau Brugues-Davi of Spain needed three sets to see off Kazakh Mikhail Kukushkin 6-7 (5/7) 6-3 7-6 (7/3) and set up a second-round meeting with fourth seed Gilles Simon.
The winner of that match will play Benoit Paire in the last eight. The Avignon-born right-hander survived a tough three-set encounter with Belgium's Steve Darcis to win 4-6 7-6 (13/11) 6-4.
Elsewhere, Victor Troicki of Russia edged out 18-year-old wildcard Louis Pouille with a 6-4 7-5 win and Michael Llodra will next face second seed Janko Tipsarevic after dispatching fellow Frenchman Kenny De Schepper 6-3 6-3.
