Tsitsipas’ birthday prank on Kyrgios

Stefanos Tsitsipas sent Nick Kyrgios an unwelcome gift through Instagram on Monday. The sixth-ranked Greek posted a picture of himself standing outside and holding up a home-made cardboard sign with a phone number and the words "call me" scrawled on it. Fans who excitedly rang it thinking it was the Greek star's number, found that the phone was turned off and quickly worked out that the number was Australian and linked to Kyrgios, who was celebrating his 25th birthday. That was confirmed when Kyrgios himself replied. "You are an absolute i****" , using stars for the last four letters and  a series of laughing emojis.                                                                                                                         --Reuters
