STUTTGART, Germany (AP) -- Nicolas Kiefer of Germany has upset third-seeded Tomas Berdych of the Czech Republic 6-3, 6-3 to move into the second round of the Mercedes Cup.

Kiefer beat Berdych for the first time in five matches. Berdych had been hoping for his second clay-court title in Germany this year, after winning in Munich. Berdych also helped the Czech Republic reach the Davis Cup semifinals by beating Argentina last weekend.

Another German, fifth-seeded Philipp Kohlschreiber, eased into the second round Tuesday by beating Diego Junqueira of Argentina 6-3, 6-2.

Fabio Fognini of Italy rallied to beat seventh-seeded Fabrice Santoro of France 5-7, 7-6 (3), 6-1.
