Spain's Roberto Carballes Baena won a three-hour final against Frenchman Alexandre Muller in Marrakesh on Sunday to claim his second ATP title.
Carballes Baena dropped the first set against his 126th-ranked opponent but rallied to earn a 4-6, 7-6 (7/3), 6-2 victory.
"I am so tired, but I am very, very happy. It was a very, very tough match," Carballes Baena said in his on-court interview.
"I tried to fight every point. I don't know what to say. I am so happy."
The 30-year-old Carballes Baena is expected to enter the top 50 for the first time on Monday after beginning this week as world number 82.
His only other tour-level title also came on clay at Quito in 2018.
