DOHA, Qatar, Jan. 2 (UPI) -- Top seed Roger Federer of Switzerland was ousted, but third-seed defending champion Younes El Aynaoui of Morocco survived in Thursday's quarterfinals of the $1 million Qatar Open.
Fifth-seeded Jan-Michael Gambill, whose last title came in March 2001, recorded a 6-4, 7-5 victory over Federer who won 58 matches and three titles in 2002.
El Aynaoui needed three sets for the first time in three matches as he rallied for a 3-6, 6-3, 6-3 victory over eighth seed Fabrice Santoro of Spain. El Aynaoui will take on Austrian Stefan Koubek in the semifinals.
Seeking his third career title, Koubek cruised to a 6-3, 6-4 victory over Swedish qualifier Andreas Vinciguerra. Mikhail Youzhny, the sixth seed from Russia, advanced to a meeting with Gambill by defeating Spaniard Fernando Vicente, 7-6 (9-7), 6-3.
