Shelton, the No. 2 seed, next faces Argentina’s Francisco Cerundolo for a spot in the final. The fifth-seeded Cerundolo moved into the last four by defeating David Goffin 6-2, 6-4.

Before the tournament, Shelton attended his first professional soccer game when Bayern Munich drew 2-2 with rival Borussia Dortmund on Saturday.

In reaching his ninth tour-level semifinal, Shelton ended Darderi’s career-best winning streak at seven matches, which included the Marrakech title.
