No shirts were necessary for Novak Djokovic following his Cincinnati Open win on Sunday ... 'cause the tennis star ripped the tee right off his chest in celebration of his big victory!!!
Just seconds after the 36-year-old won a grueling, 3-hour-and-49-minute match over Carlos Alcaraz in Ohio ... he ditched his top to commemorate the occasion.
At first, Djokovic dropped to the ground in disbelief over his thrilling win ... and then, after sharing an embrace with Alcaraz, he decided to tear the polo straight off his body.
