Nadal, who had been watching from the bench with the rest of the Spanish team, hopped on to court to console Alcaraz and Granollers.
Both looked despondent as they sat with their heads bowed, listening to the victorious Dutch players celebrating reaching the semi-finals.
Many stayed in the 11,500-capacity Palacio de Deportes arena, chanting “Rafa, Rafa, Rafa” for one final time as they waited for Koolhof and Van de Zandschulp to conclude a post-match interview.
When the moment came for Nadal to take centre stage, he was given another standing ovation and a round of applause lasting over a minute.
Nadal’s family, including his wife Mery, young son Rafael junior, parents Ana Maria and Sebastian and sister Maribel, were present in the stands.
Long-time members of his backroom team wore T-shirts depicting the logo of the ‘Raging Bull’ which became his moniker, inspired by his indomitable fighting spirit.
After finishing a heartfelt speech in Spanish, the main lights dimmed and a spotlight surrounded Nadal.
He stared at the court for a few moments, chewing his lip as he fought back the tears.
The next part of the celebration was a video montage of career highlights and personal messages from sporting superstars, including tennis legends Roger Federer, Novak Djokovic, Serena Williams and Andy Murray, along with footballers David Beckham, Andres Iniesta and Raul, and golfer Sergio Garcia.
Another elongated spell of applause followed before he walked off the court, blowing kisses on the way, for the final time as a professional player.
