Bernard Tomic and Nick Kyrgios went head-to-head for the first time in their careers at the Kooyong Classic Exhibition Event overnight, with the all-Australian contest bringing up some interesting moments.
Tomic won the clash 6-3, 6-4, with both players preparing to compete in the Australian Open when the tournament commences in Melbourne next week.
However, Tomic, who has returned from a tough injury spell that saw him drop down to 243 in the world rankings, won the match in controversial fashion.
With two match points to play with, Tomic begun bouncing a ball in preparation to serve when he casually flicked another ball between his legs which had enough power to go over the net and into Kyrgios' service box.
As the serve went for an ace which wrapped up Tomic's victory, there was understandable confusion - see below.
Although some might have deemed the serve disrespectful, Kyrgios was full of praise for his compatriot and predicted Tomic to do well in the upcoming Grand Slam.
"I don't think there has ever been a player like BT," Kyrgios said following the match.
"He won a title last year and it looks like he is carrying a bit of momentum which is good to see.
"He can make a run at the Australian Open, for sure.
"It is great to see him back out here as I know he was going through some rough times.
"It's sad to see a talent like that go down and just get beaten down so to see him with a smile on his face, embracing the crowd, he loves that."
Meanwhile, Tomic, who missed last year's Australian Open, has lofty ambitions for the 2019 competition.
He said: "I've made third or fourth round many times and lost to the great players of the world so my target is to make another quarter or maybe a semi if I can."
