New York Open: Fifth seed Kei Nishikori blanks Russia’s Evgeny Donskoy in straight sets to enter quarter-finals

Nishikori broke Donskoy’s service twice in the opening set to pull away and then earned another crucial break with the second set tied at 2-2. The 28-year-old won 84 percent of his service points. It was another positive step for Nishikori, who last August suffered a right wrist injury which forced him to miss last year’s US Open and the Australian Open at the start of the season. The former US Open finalist has since made his comeback to competition by playing in Challenger events.
