Stefanos Tsitsipas sent his tennis mate Nick Kyrgios a special 25th birthday greeting. Unfortunately for Kyrgios, it contained too much information.
Tsitsipas, who is Greek, sent an Instagram message to Kyrgios, who is an Australian of Greek heritage. In it, Tsitsipas held up a cardboard sign that said "Call me" and listed a cell phone number. Those expecting to get Tsitsipas on the line instead got a different message.
The phone was turned off.
"You are an absolute idiot ... everyone stop calling me!!!!!" Kyrgios responded to his sometimes doubles partner in a social media post.
Later Tsitsipas returned to Instagram with another cardboard sign saying: "Stop calling Nick."
The number has since been disconnected.
Professional tennis tours have been suspended amid the coronavirus pandemic.
