Top-seeded Kei Nishikori was beaten 7-6 (4), 6-4 by Alexandr Dolgopolov on Sunday in the final of the claycourt Argentina Open.

Dolgopolov won his third ATP singles title and his first in five years. It was also the Ukrainian’s first victory over his Japanese opponent after losing their previous five head-to-head matches.

Nishikori, who is No. 5 in the ATP singles rankings, has won 11 singles titles, but only two on clay.

Nishikori will also be the topseeded player in next week’s Rio de Janeiro Open, with Dominic Thiem of Austria No. 2. Dolgopolov will be unseeded on clay in Rio.
