Third-seeded Borna Coric beat eighth-seeded Jiri Vesely 7-6 (5), 7-6 (5) on Saturday to reach the Grand Prix Hassan II final, where he will bid for his first career title.
The 19-year-old Croat will take on Argentine Federico Delbonis, who eliminated Spaniard Albert Montanes 6-4, 6-3.
Delbonis, who won the only title of his career two years ago at Sao Paulo on indoor clay, has never faced Coric.
Coric, ranked 48th, lost his only career final in January on an outdoor hard-court at Chennai, India.
After both players broke once in the first set, Vesely opened up a 3-1 lead in the second, but Coric broke back against the Czech and sealed victory on his second match point.
