David Ferrer beat his Spanish Davis Cup teammate Nicolas Almagro 6-3, 7-5 on Friday to reach the semifinals of the Valencia Open.
The fifth-ranked Ferrer was little troubled on the hard indoor surface as he improved to 12-0 against an opponent who will become his teammate next month in the Czech Republic when Spain looks to defend its Davis Cup title.
Ferrer has won the Valencia title twice and has never lost to Almagro, a record that includes four encounters this season.
Almagro had a triple-break chance in the sixth game of the second set but failed to turn it around as Ferrer held before breaking in the 11th game. Ferrer saved his fourth break point in the final game before clinching the win when Almagro hit long.
Earlier, Jurgen Melzer and Alexandr Dolgopolov each won to set up their own semifinal match.
Melzer, who hasn't dropped a set at the tournament, beat David Goffin of Belgium 7-6 (7), 6-4. The Austrian overcame a poor first serve, including seven double-faults.
