ROTTERDAM (Agencies) - Third seed David Ferrer became the first upset victim at the ATP Rotterdam Open on Tuesday as the Spaniard lost 6-3, 6-4 to Finn Jarkko Nieminen in the opening round. Little more than a week after playing an Australian Open semi-final following his quarterfinal knockout of world number one compatriot Rafael Nadal, Ferrer found himself adrift indoors at the Ahoy stadium. The number six who won his first nine matches of the season, was unable to duplicate his first-round win over Nieminen in Melbourne, exiting in 75 minutes after holding a 3-1 lead in the second set as he attempted a fight back. Nieminen also won the pair's only other meeting in a Challenger a decade ago. Ferrer produced seven aces but lost serve four times as he went down to his second loss of the season. The 43rd-ranked Finn, a 2006 semi-finalist, will play Serb Viktor Troicki in the second round after improving his modest record this season to 2-3. The victory was the first for Nieminen in a month since Doha, a victory followed by first-round defeats in Sydney and Melbourne. Croatian seventh seed Ivan Ljubicic defeated Ukrainian Sergiy Stakhovsky 7-6 (7/3), 6-3.
