Grigor Dimitrov tops Russia's Karen Khachanov at tennis tournament in Miami after comeback

This is Dimitrov's fifth success in a total of six matches against Karen Khachanov.

Grigor's next opponent in Miami will be Brandon Nakashima. The Bulgarian tennis player achieved victory number 100 in the Masters tournaments on hard court.

"We know each other quite well and we train together often. We don't have any special secrets. The difference comes in a few points. In the first set I won more points, but I lost it. I need to raise my level at certain moments. A physically difficult match, but I need exactly such matches. I know that I can play much better tennis," commented Dimitrov on the court after his victory against Khachanov.
