Since 2008, Grigor Dimitrov has graced the ATP Tour with flair and style comparable to Roger Federer. Yet the Bulgarian has developed a personality and style all his own, and while he hasn't won a major yet, he's become the undisputed best Bulgarian ATP player in history.

In June while playing the Adria Tour exhibition, Dimitrov announced he had tested positive for COVID-19.

Borna Coric, Novak Djokovic, Goran Ivanisevic and Viktor Troicki also tested positive that week in Croatia. 

Dimitrov has since been struggling to return to the court, going 0-2 over the weekend at the Ultimate Tennis Showdown 2 in France. 

"The virus was hard on me," Dimitrov said. "I stayed home for about a month...I was not breathing well, I was tired, I had no taste, no smell, so it was no fun."

As Dimitrov tries to get back into top shape in France, let's take a closer look at his career.
