Playing his first match since pushing Roger Federer to the limit in Wimbledon's third round, Benneteau took the first set but was broken four times in the next two as he slumped to a 3-6 6-4 6-1 defeat.

Spain's fifth seed Feliciano Lopez was fortunate to survive against Romania's world number 102 Adrian Ungur, finally nudging through 2-6 6-4 7-6 (9/7) in two hours and three minutes.

Latvia's Ernests Gulbis beat Filippo Volandri 7-6 (7-2) 4-6 6-3, while there were also wins for Thomaz Bellucci and Lukasz Kubot.

Like Lopez, German qualifier Dustin Brown was a final-set tie-break winner, seeing off Sergiy Stakhovsky, while Jan Hajek also progressed when Edouard Roger-Vasselin retired when 4-1 down in their opening set.
