The pair were separated by just one spot in the ATP rankings prior to the clash, but once Edmund recovered from an early wobble he charged to a 7-5 6-1 victory in 80 minutes.
Evans picked up his first win on clay since 2013 in the Davis Cup dead rubber against France’s Julien Benneteau earlier in April – albeit a match that saw him briefly face three players as his opponents took it semi-seriously.
Still, it looked to have had a positive impact as he raced into an early 4-1 lead in the first set on his unfavoured surface.
However, Edmund soon found his stride to reel off 12 of the next 14 games to book a duel with fourth seed Rafael Nadal.
