World number four Stefanos Tsitsipas suffered a shock straight-set defeat by American Frances Tiafoe on day one at Wimbledon.
Third seed Tsitsipas, who reached the French Open final earlier in June, was beaten 6-4 6-4 6-3 by the impressive world number 57 Tiafoe on Court One.
It is the third time in four attempts the 22-year-old Greek has exited Wimbledon in round one.
Tiafoe meets Canada's Vasek Pospisil or Spain's Roberto Carballes Baena next.
The 23-year-old reached the Queen's Club quarter-finals two weeks ago, but this was the first time he has ever beaten a top-five ranked player.
