Marrakech - Fourth-seeded Federico Delbonis beat third-seeded Borna Coric 6-2, 6-4 on Sunday to clinch the clay-court Grand Prix Hassan II for his second career title.
The Argentine was more consistent on his serve in their first-ever meeting, winning 80 percent of first-serve points and saving the three break points he faced against Coric.
The 25-year-old Delbonis, who broke Coric's serve three times, won his first title two years ago at Sao Paulo on indoor clay.
"I played at a great level today," said Delbonis, who did not drop a set all week.
Coric, ranked 48th, lost his other career final in January on an outdoor hard-court at Chennai, India.
The 19-year-old Croat said "I had an opportunity in the second set but unfortunately I couldn't break him."
