What a number for the South Tyrolean champion during a training session at the Master 1000 in Monte Carlo! Jannik Sinner first tries the serve, then responds with the scorpion move, hitting the ball behind his back with his raised foot. Sinner is currently playing the doubles with Bergs in Monte Carlo (against Machac and Ruud), while he will take to the court for the singles on 7 April (Ig: @marco_giulini).
