(Reuters) - Kei Nishikori broke the serve of American John Isner once in the second set and again in the third set and that was enough for the rising Japanese player to claim the Citi Open title in Washington, D.C. on Sunday.
The second-seeded Nishikori beat the big-serving Isner 4-6 6-4 6-4 to celebrate his third title of the season and 10th of his career.
“It’s been an amazing year so far,” said the 25-year-old Nishikori, who will move up to fourth from fifth in the world rankings. “I’ve had some good Grand Slams, too.”
Nishikori now looks forward to taking the next step at the U.
