Russian qualifier Daniil Medvedev stunned home favourite Kei Nishikori in Tokyo on Sunday, winning the final of the Japan Open 6-2 6-4 in just over one hour.
The Japanese was aiming for his third title on home soil.
But Medvedev came out of the blocks fast and Nishikori could not cope with the big-hitting Russian who broke his serve at the second time of asking.
After that it was a story of mistakes by world number 12 Nishikori and consistent serving by Medvedev who strolled to a 6-2 first set in just 25 minutes.
Nishikori corrected issues with his own serve in the second set but still could not have an impact on Medvedev’s service games.
He thus took only one point on the Russian’s serve during the entirety of the second set.
Medvedev bided his time and broke a tired Nishikori, whose final shot was another wild miss, to wrap up the victory and secure a third ATP title of the season.
Nishikori has now lost eight ATP finals since his last victory, which came at the Memphis Open in February 2016.
