Atletico Paranaense advanced to the final of the 2016 Sait Nagjee Trophy at the expense of Shamrock Rovers thanks to a second-half strike from Yago Cesar da Silva.
The League of Ireland side were unlucky not to get on the scoresheet, having hit the woodwork on three separate occasions. Gary Shaw was the first Hoops player to be denied by the woodwork as his 10th minute effort rebounded off the post.
A series of Rovers corners came to nothing before the Brazilian side carved out a good chance of their own with Joao Pedro firing just over. Craig Hyland denied Victor Feitosa before Dean Clarke hit the post as the two sides started the second-half with attacking intent.
Atletico Paranaense took the lead just after the hour mark when Yago struck from range after a roving run into the Hoops half.
The Hoops pushed for an equaliser, and went close when Brandon Miele hit the bar, but could not find the game-tying goal.
Atletico Paranaense now meet either Dnipro or Watford in the final, while Shamrock Rovers return to Ireland ahead of the new SSE Airtricity Premier Division season.
