David Ferrer beat Spanish Davis Cup teammate Nicolas Almagro 6-3 7-5 to reach the semi-finals of the Valencia Open on Friday.

Fifth-ranked Ferrer had little trouble as he improved to 12-0 against an opponent who will be 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.

“It was my best game of the week,” Ferrer said.

“Today I knew had to play at my best level or I wouldn’t win.”

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.

Ferrer next plays qualifier Ivan Dodig after he defeated fellow Croatian Marin Cilic 6-2 7-6 (8-6).

Earlier, Jurgen Melzer and Alexandr Dolgopolov each won to set up their own semi-final match.

Melzer, who hasn’t dropped a set at the tournament, beat David Goffin of Belgium 7-6 (9-7) 6-4. The Austrian overcame a poor first serve, including seven double-faults.

Dolgopolov defeated defending champion Marcel Granollers 6-0 6-2. The Ukrainian was perfect on his first serve in the first set.

“It was for sure easier than expected. He was frustrated and he wasn’t playing his best tennis,” said the 21st-ranked Dolgopolov, who broke the Spaniard five times.

“I had no chance of coming back,” said Granollers, who had reached the last two finals in Valencia.

Granollers is expected to lead Spain’s doubles team in Prague.
