Argentina's Carlos Berlocq claimed the Portugal Open title on Sunday by beating top seed Czech Tomas Berdych 0-6, 7-5, 6-1.
It was Berlocq's second career title, and he described it as a dream come true.
The world number 62 becomes the sixth tournament winner over the age of 30 this year on the ATP with his victory in two hours, nine minutes against the world number six, reports Sport24.
Berlocq said that to beat one of the best in the world in Berdych was very rewarding. He added that it was an honour to play and to win the final.
Berlocq became the fifth Argentine to win at the venue after Juan Martin del Potro (2011, 2012), David Nalbandian (2002, 2006) Gaston Gaudio (2005) and Juan Chela (2004).
Berdych, on the other hand, was bidding for the ninth title of his career.
Berlocq had earlier won in Bastad in Sweden last summer.
