One of the ball boys makes an amazing catch during the Federer Nadal Semifinal match at the Australian Open. Then there was a cricket reference to Ricky Ponting, and the crowd goes crazy!
Along Lleyton Hewitt in double for the last tournament of his career at the Australian Open, Sam Groth made a double fault to gave the break to their opponents, on what was probably the last serve of his career. His racquet didn't survived to that.
Andy Murray wasn't maybe totally satisfied by his haircut or more probably some of his front hairs were disturbing him. He made a little on-court adjustment to it during his match against Rafael Nadal in London (ATP Finals 2015, Masters).
