Wild card Aslan Karatsev defeated South African qualifier Lloyd Harris 6-3, 6-2 in the final of the Dubai Championships for his first ATP Tour title.
The 27-year-old Karatsev saved the two break points he faced to win in 1hr 15m, becoming the third Russian champion this season. Daniil Medvedev and Andrey Rublev are the others.
The 42nd-ranked Karatsev has only been beaten by Novak Djokovic and Dominic Thiem in 14 matches this year. He beat top-seeded Rublev 6-2, 4-6, 6-4 in their semi-final, when he claimed his fourth consecutive win over a seeded player at the hard-court tournament.
Harris was also going for his first title after becoming the first qualifier to reach the final. He had gone into the event ranked No81 in the world but is set to move into the top 70 when the new rankings are released.
