David Ferrer will defend his Copa Claro title in the final against Stanislas Wawrinka of Switzerland.

Ferrer defeated fellow Spaniard Tommy Robredo 6-3, 6-2 Saturday on the outdoor clay, and Wawrinka defeated Nicolas Almagro 6-3, 7-5 to reach his first final in the Argentine capital. He lost his two other semifinal appearances, including last year to Almagro.

"It was a tough match physically,'' said Ferrer, who has played three straight days. "Maybe it was my best match of the week.''

Ferrer won in Auckland, New Zealand, last month and will be going for his 20th career title.

Wawrinka broke Almagro in the 11th game of the second set and won when Almagro retuned his serve wide.

Wawrinka aims for his fourth ATP title.
