Alexandr Dolgopolov upset top-seeded David Ferrer in the quarter-finals of the Open de Nice with vital victory.

Dolgopolov, the world number 23, held his nerve despite a disastrous second set and now has the chance to reach his second ATP Tour final of the season when he faces Romania's Victor Hanescu.
Hanescu, the world number 69, ended the run of Dutch lucky loser Robin Haase. Haase was trailing 6-2 2-0 when he was forced to withdraw with a right ankle injury.
Second seed Tomas Berdych was an impressive 6-1 6-4 winner over Latvia's Ernests Gulbis. He will play world number 12 Nicolas Almagro in the second semi-final after Almagro beat fellow Spaniard Pablo Andujar, also 6-1 6-4.
