Top seed and defending champion David set victors, while third seed Gael Monfils came up a quarterfinal loser Friday at the $1.905 million Valencia Open 500 tennis event.
Ferrer handled former top-five star Nikolay Davydenko 6-3, 6-4 in 1 hour, 21 minutes on the indoor hardcourts at Valencia's City of Arts and Sciences. The gritty Spaniard tallied three service breaks, compared to only one for the Russian loser.
The world No. 5 Ferrer topped Marcel Granollers in last year's all-Spanish finale, was also the Valencia titlist in 2008, and was the runner-up here in 2005.
