Serena Williams and Grigor Dimitrov share practice court

Following the Australian Open semi-final run, the 23-time Major champion Serena Williams is preparing for new challenges that should come in three weeks in Miami.

Following that Naomi Osaka loss in Melbourne, Serena left the press conference in tears and raised many concerns ahead of the season's remaining events. Instead of looking back, Williams is already on the practice court, working hard on her game and sharing the training sessions with her great friend Grigor Dimitrov. Serena and Grigor shared the footage from their practice run, enjoying the time on the court and praising each other.

Serena and Grigor have been friends for years, and they often trained together in the past. The Bulgarian needed some time off the court following the Australian Open quarter-final loss to Aslan Karatsev, injuring his back and barely leaving the court on two legs.
