Sagar Kashyap (third from left in the background) umpired Roger Federer's Australian Open final.
Kashyap was sat in the high seat overlooking Federer’s Australian Open quarter-final match against Tomas Berdych when he called a shot out.
He then quickly reversed his decision to in, but the Swiss star challenged the call.
Kashyap was proved to have eventually got to the right conclusion as Hawk-Eye showed the effort was 1mm in - much to the frustration of Federer.
But the Indian match official was delighted to have come out on top in such a high-intensity atmosphere.
