Footage has captured Greek tennis star Stefanos Tsitsipas whacking himself in the forehead in one of the craziest tennis meltdowns in recent memory.
Tsitsipas went down to defending champion Alexander Zverev in their Citi Open semi-final in Washington.
Zverev advanced to the decider to become the first player to win 40 ATP Tour matches in 2018.
But it was his opponent’s tennis tantrum for the ages that captured headlines for the wrong reasons after the match.
Tsitsipas made just 41 per cent of his first serves in a frustrating opening set and the Greek player let his anger boil over in dramatic style.
The 19-year-old repeatedly smacked himself in the head as fans and commentators watched in concern before the change of ends.
The ill-advised tactic didn’t achieve the desired effect as Zverev went on to secure a 6-2 6-4 triumph in under 90 minutes.
Tsitsipas isn’t the first man to throw a massive tennis tantrum during this tournament, with Frenchman Benoit Paire copping a whopping fine after his racquet-smashing rampage.
Zverev’s straight sets win continues a fine year for the German that already includes two tour titles in Munich and Madrid.
He will add a third in Washington if he can continue his form at the tournament where his overall record stands at 15-2.
Zverev, who has won 40 matches and lost just 11 in 2018, did not face a single break point against Tsitsipas in the semi-final and dropped only a solitary point on his first serve in the opening set.
