Santiago Giraldo ended hopes of Nicolas Almagro building on his triumph over world number one Rafael Nadal with a 7-5 6-3 victory to book a place in the final of the Barcelona Open.
The Colombian - who knocked out number three seed Fabio Fognini in round two - continued his fine recent form with a comfortable win, which included six aces and losing just one service game, to wrap up victory in one hour and 25 minutes as he moved into a second ATP Tour final.
On Sunday, the 26-year-old will meet Kei Nishikori, the first Japanese player to reach the final of the Barcelona Open.
Nishikori took 86 minutes to dispatch ninth seed Ernests Gulbis 6-2, 6-4.
"I was very happy to see lots of Japanese people congratulating me after the match," said Nishikori, who in February claimed a fourth ATP title at the US National Indoor Tennis Championships at Memphis.
"I love coming to Spain to play, I am playing great, and there have not been any easy matches."
