Di Nenno and Stupaczuk have yet to miss a semi-final in 2023, making it eight out of eight on Friday with their victory.
With Arturo Coello, Agustin Tapia, Juan Lebron and Alejandro Galan all absent, Di Nenno and 'Stupa' have a golden opportunity to claim their first title of the season.
The Argentinians did not feel the pressure of their role as favourites, taking care of Ruiz and Tello in straight sets.
