Watch: German tennis star Alexander Zverev frightens ball Boy

Alexander Zverev defeated Nikoloz Basilashvili in his second round match at the ATP Shanghai Masters and while celebrating his win, the German tennis star gave a ball boy the fright of his life. 

With the match evenly poised in the first set against the China Open champion, Zverev ran down a drop shot with ease before firing a backhand winner down the line to secure a crucial break of serve.

Zverev roared his delight and pumped his fist in celebration but the ball boy - just a yard away - was taken aback as he leaned back in stunned shock.

The hilarious incident was caught on camera and quickly went viral.

Zverev faced tough resistance but overcame the Georgian 7-5, 6-4 to reach the third round. The fourth seed will next play Australia's world-ranked 33 Alex de Minaur.
