GSTAAD, Switzerland (AP) Defending champion Pablo Andujar of Spain advanced to the Swiss Open quarterfinals by beating Dusan Lajovic of Serbia 7-5, 6-2 on Wednesday.

Fourth-seeded Andujar next faces another former champion on the Gstaad clay courts, two-time winner Thomaz Bellucci of Brazil.

Bellucci beat Stephane Robert of France 6-3, 6-2 in their second-round match in the high-end ski resort.

Seeded players advanced in all four matches on a rain-affected day.

Second-seeded Feliciano Lopez of Spain rallied to win his first singles match since getting married last week.

Santiago Giraldo of Colombia, the eighth seed, eased past Marsel Ilhan of Turkey, 6-2, 6-3.
