The duel had one more twist in store when Michelsen pegged back the early fifth-set break, but it was to little avail.
His fresher opponent hammered home the advantage with one final break to prevail after four hours and 16 minutes.
Following in the footsteps of his idols Rafael Nadal and Carlos Alcaraz, Jodar was intent on forging his own path, quick to point out he was still far from the finished product.
“I'm an aggressive player who likes to dominate the points, but I think here on clay, you know, you have to defend a little bit more, so I am trying to develop that game as well,” he said.
“I'm now trying to develop all my weak points, like, for example, the forehand, the serve, the return. I think those are things that I still have to develop.”
