Nick Kyrgios is making headlines again.

Yesterday, the 23-year-old forgot to pack his trainers in his bag for his first round match against Denis Kudla.

In this match, the Australian was given a point violation for his on-court singing, which included some expletives, as well as being handed a code violation by the chair umpire for striking a ball into Centre Court.

This time it is for the bizarre method of ‘tanking’ during the second set against the Croatian Borna Coric in the second round of the Cincinnati Masters.

Kyrgios won an entertaining first set 7-6 after having dominated the tie break 7-1.

Coric was 2-0 up in the second set when Kyrgios’ temper rose.

Following one of Coric’s passing shots being called in, an incredulous Kyrgios smashed the ball high into the night sky before ranting at the umpire.

Coric won the first four games of the second set. This resulted in Kyrgios’ extraordinary tactics of ‘tanking’ with the Australian saying to his team at one change of ends, ‘You’ll never see a bigger tank than in the next three games’.

‘Tanking’ means giving little effort in tennis terms.

It wasn't just his team he was getting into altercations with, however, as there were a couple of moments he exchanged words with the crowd.

Firstly, he turned to the crowd and said: "You wanna be a referee? You're all eligible."

This was then followed up later in the match after a fan tried to shout him some encouragement.

The fan yelled "Dig in Nick," to which Kyrgios responded with, "It's five to zero mate."

"The second set, when I was 4-0 down, I knew there was no real point going out there and competing and obviously waste energy trying to battle back,” said Canberra-born Kyrgios, who hit a tame return and began walking to his chair before Coric had even finished off the point when it was set point in the second set.

"I knew at 4-0, if I lost the set 6-0, I was going to be serving first in the third set. I think I carried a lot of momentum from the first game, and it ended up being a smart move."

"I knew I was always going to compete in the third set."

The Australian’s unique methods turned out to be justified after he won the third and final set 6-3 with some spectacular shots, and therefore won the second round match.

He will now play against the winner of Hyeon Chung’s contest with Juan Martin del Potro.

Kyrgios’ fans will hope he goes one better than last year at the Cincinnati Masters, where he lost to Grigor Dimitrov in the final.
