Alexander Zverev snaps racket on leg during French Open clash with Dusan Lajovic
Zverev had been broken twice in the opening set, which he lost 6-2, and lost a long rally in the third game of the second set to drop his serve once again.
The German missed a backhand from the baseline and slammed his racket into the court in anger at going 2-1 down.
The 21-year-old then investigated the damage and bent the offending object over his leg, snapping the frame and rendering it useless.
If the move was supposed to rouse him to a comeback, it did not initially work. Lajovic consolidated the break of serve to love in the very next game and Zverev was staring down the barrel of a second-round defeat to a player ranked 57 places below him in the world.
