SOFIA, Bulgaria (AP) Second-seeded Viktor Troicki reached the Sofia Open quarterfinals after defeating German qualifier Daniel Brands 6-4, 6-3 on Thursday.
Troicki, through to his second quarterfinal in three tournaments this year, said of Brands: ''He has a very aggressive game, which I usually like to play against, and that's maybe why I played really well.''
Top-seeded Roberto Bautista Agut of Spain also advanced after Filip Krajinovic of Serbia withdrew before their second-round match because of a right shoulder injury.
Bautista Agut, the top seed in an ATP event for the first time, has eighth-seeded Adrian Mannarino of France in the quarterfinals. They are 2-2 in career head-to-heads.
Also through was fourth-seeded Andreas Seppi of Italy, who beat Thiemo de Bakker of the Netherlands 6-2, 6-1, and will try to beat seventh-seeded Martin Klizan of Slovakia on Friday for a third straight time on tour.
